Shock waves passing through a metal sample can produce ejecta particulates at a metal-vacuum interface. Holography records particle size distributions by using a high-power, short-pulse laser to freeze particle motion. The sizes of the ejecta particles are recorded using an in-line Fraunhofer holography technique. Because the holographic plate would be destroyed in an energetic environment, a high-resolution lens has been designed to relay the scattered and unscattered light to a safe environment where the interference fringes are recorded on film. These interference fringes allow particles to be reconstructed within a 12-mm-diameter, 5-mm-thick volume. To achieve resolution down to 0.5 mu m, both a high-resolution optical relay lens and ultraviolet laser (UV) light were implemented. The design and assembly of a nine-element lens that achieves > 2000 lp/mm resolution and operates at f/0.89 will be described. To set up this lens system, a doublet lens is temporarily attached that enables operation with 532-nm laser light and 1100 lp/mm resolution. Thus, the setup and alignment are performed with green light, but the dynamic recording is done with UV light. During setup, the 532-nm beam provides enough focus shift to accommodate the placement of a resolution target outside the ejecta volume;this resolution target does not interfere with the calibrated wires and pegs surrounding the ejecta volume. A television microscope archives images of resolution patterns that prove that the calibration wires, interference filter, holographic plate, and relay lenses are in their correct positions. Part of this lens is under vacuum, at the point where the laser illumination passes through a focus. Alignment and tolerancing of this high-resolution lens will be presented, and resolution variation through the 5-mm depth of field will be discussed.

Recently, telescopes with segmented primary mirrors are becoming increasingly popular due to their ability of achieving large apertures without the inconveniences caused by the fabrication and handling of monolithic surfaces with 8m (or over) in diameter. The difference in position of each pair of adjacent segments along the local normal of their interface (called piston hereafter), however, needs to be precisely measured in order to provide a diffraction-limited image. If a system yielding the nanometric accuracy required in piston measurements worked in daylight hours, the resultant saving in observation time would be an important advance on a majority of the state-of-the-art piston measurement systems. An interferometric piston measurement instrument accomplishing such objectives has been designed starting from the usual Michelson configuration at the CD6 (Terrassa, Spain), and its final test has been carried out in the test workbench of the Institute de Astrofisica de Canarias (IAC, Canary Islands, Spain). Its optical layout relies on projecting the reference arm of the interferometer onto one of the segments of the pair considered, along the direction of the local normal to the surface while the measurement arm is projected onto the interface which divides the pair of segments considered. The field of view and its illumination are calculated to be equivalent in both segments. The lateral shift of the fringes in both interferograms determines the piston error present. A combination of monochromatic and white light is used, in order to remove the lambda /2 phase ambiguities present in piston measurements without losing the required resolution in the measurement. In this paper, the optical design of this interferometric piston measurement instrument will be presented. The particular configuration used in the interferometer, the implementation of an imaging system allowing to see both the interface of the segments and the interference fringes, the effect of the ext

ISBN: (纸本)0819432652

This paper describes the design of a camera system capable of acquiring stars during both the day and night cycles of a high altitude balloon flight (35-42 km). The camera system will be filtered to operate in the R and I bands (similar to 600-1000nm), and simulations have been run using MODTRAN atmospheric code to determine the worse case sky brightness at 35km. With a worse case daytime sky brightness of 2x10(-5) W/cm(2)/sr/mu m at 600nm, the sensitivity of the camera system will allow acquisition of at least 1-2 stars/degrees(2) at star magnitude limits of 7.8-8.1. The system will have an F2.8, 64.3mm diameter lens and a 1340 x 1037 CCD digitized to 12 bits. The CCD is comprised of 6.8 mu m x 6.8 mu m pixels with a well depth of 45,000 electrons and quantum efficiency of 0.54 at 700nm. The camera's field-of-view will be 6.33 degrees(2) and provide attitude knowledge to 8 arcsec or better. A test flight of the system is scheduled for fall 1999.

New approaches for optical data storage (ODS) applications are needed to meet the future requirements of applications in multimedia, archiving, security, and many others. Commercial data storage technologies are moving to three-dimensional (3D) materials, but the capacity is limited by the fabrication cost and the number of layers that can be addressed using the reflection-based storage mechanism. We demonstrate here storage systems based on co-extrusion of multilayer (ML) films that can overcome these problems. The organic roll-to-roll films produced can easily be produced hundreds of meters in length, in a far simpler and cheaper manner than current manufacturing methods such as spin coating and lamination. The medium consists of alternating active and buffer layers, and data storage is demonstrated by writing images in 23 layers of 78 mu m thick films by fluorescence (FL) quenching of an organic dye. The areal data resolution is at the diffraction limit of the CW Blu-ray (BR) laser employed, and the co-extrusion technique allows for small layer spacings, leading to a total bit density 1.2 Tb/cm(3). We anticipate materials already demonstrated successful for 3D ODS will be adapted to this technique, as well as new systems developed, to take full advantage of this medium.

A lunar orbiting space terminal was recently developed as part of NASA's Lunar Laser Communications Demonstration program. The space terminal uses a 10 centimeter, inertially-stabilized telescope and a 0.5 watt beam to transmit data at up to 622Mbps between the Moon and one of several ground terminals on Earth. Tight coupling between analysis and testing was used to ensure both performance and survival requirements were met in the operational and non-operational vibration environments. Performance requirements were driven by the need to meet a 4.2 mu rad pointing stability requirement in the operational vibration environment. A highly-correlated FEA model was developed using vibration testing to extrapolate the behavior of the system beyond the practical limits of the vibration test bed. The launch load non-operational vibration environment was simulated through both analysis and testing using force-limiting to avoid over designing and over testing the sensitive optics. The iterative and associated challenges of the vibration analysis and testing effort are discussed to show how those efforts helped enable the successful launch, deployment, and ultimately demonstration of NASA's first space laser communications program.

Over the last two decades solid immersion objectives have been developed for various applications, offering the opportunity to achieve a higher resolution than is possible for conventional air objective lenses. For semiconductor applications hemispherical solid immersion lenses (SILs), incorporating tips fabricated in semiconductor materials with a high refractive index (up to n = 3:5 for silicon, for example) are commonly used. With such high refractive index materials it is possible to design an objective with a numerical aperture of NA = 3:2. An apochromatic color correction is mandatory if a broad spectral range from lambda = 1200 nm to lambda = 2000 nm is required. It is well known that glasses with anomalous partial dispersion must be used to realize apochromatic color correction. It will be shown that the anomalous partial dispersions of some glasses in the IR range differ from the known behavior in the visible region. Therefore, glass selection plays a significant role for the design of a high NA broadband IR objective and will be discussed. Monte Carlo tolerance analysis shows that even with state of the art manufacturing capabilities the tolerance induced aberrations of an objective with NA = 3:2 will lead to a dramatic loss of image performance, indicated by a significant drop in the Strehl-ratio. This becomes even worse when the interface of the exchangeable hemispherical SIL tip with the main objective is considered. With the aim to manufacture such objectives within a stable production process it makes no sense to overload the requirements regarding the NA. Therefore, due to manufacturing issues the numerical aperture of this objective has been restricted to NA = 2:9. Wave front measurements of the manufactured objectives shows Strehl-ratios of SR > 97 % which guarantees a diffraction limited resolution.

We present a design and tolerancing approach that permits the achievement of a high degree of spatial and spectral uniformity of response from a pushbroom imaging spectrometer. Such uniformity of response is crucial for the extraction of accurate spectroscopic information from remotely sensed data. The spectrometer system example comprises two independent spectrometer modules covering the 400-2500 nm range, separated through a dichroic mirror. The relative merits of alternative approaches are briefly reviewed before concentrating on the problem of building a flight-worthy system that can approximate its design performance. The tolerancing approach requires simultaneous monitoring of many parameters, and specifically: overall image quality, spectral distortion, spectral MTF variation with field, spatial distortion, spatial MTF variation with wavelength, and slit magnification to within a small fraction of a pixel. It is shown that the wavefront error alone or even supplemented by distortion figures is insufficient for characterizing a system with high response uniformity. Tolerance values on the components and their positioning are primarily guided by the need to achieve the same magnification between the two spectrometer modules, as well as by the interferometric alignment method.

Infrared optical systems require a range of exotic materials, many with large indices of refraction. The mismatch in the index between the optical element and the surrounding medium can result in reflection losses that approach 50%. Antireflection (AR) coatings are applied to these elements in order to minimize "ghost" reflections and improve the optical transmission through a system. The coatings are designed to be highly transparent;however, significant infrared absorption has been observed in some AR coatings. Likely candidates for the loss mechanism are water trapped into the optical coatings during deposition and water being incorporated into coating voids or grain boundaries during exposure to ambient humidity. Five different AR coatings have been procured from four manufacturers to study the cause of the observed losses. Upon receipt of the coated samples, infrared transmission measurements were made which showed the presence of incorporated water/hydroxyl, as evidenced by reduced transmission around 2.9 mu m. Four of the five sample types placed in laboratory air for two months continued to absorb water, whereas those placed in flowing dry nitrogen showed no change. Samples placed in a humid environment for one, three and ten days also showed additional water incorporation with the magnitude of the change in transmission on the order of that observed with the two-month air exposure.

Multi-beam scanning is the effective method for high speed and high definition in Laser Printing, and there are three systems for this method as fellows. 1) Laser Diode (LD) Array system 2) System for dividing a single light source 3) System for combining beams of multiple LDs by optical devices Each of these systems has both advantage and disadvantage, and which one to use among these three depends on application requirements. The third system above allows for the use of conventional LDs and therefore it is low cost and offers a large degree of freedom in selecting light sources. We have already developed a Two LD Prism-based Light Source Unit that uses a C, prism to combine the beams emitted by two LDs. This system achieves stable optical characteristics with any conventional scanning optical elements. We have further enhanced this system. We have determined an optimum design that includes scanning lens and have developed the Two LD Beam-crossing Light Source Unit which performs multi-beam scanning using two LDs without a prism. In this paper, we report on recent multi-beam-scanning technologies and introduce our newly developed the Two LD Beam-crossing Light Source Unit.
