Conference on current developments in Lens design and optical engineering V

We present a method for measuring an optical system's effective focal length with a single mode fiber array and a wedge prism. Light emitted by the input fiber near the focal plane is collimated, reflected back in two angularly separated beams, and detected by the output fibers in the auto-collimation configuration. Measurement precision of a Micron can be achieved due to the precision of fiber spacing and the position sensitivity of single-mode coupling. Absolute accuracy depends on factors such as optical design configuration, metrology, aberrations, and environmental control, and can be better than 10 micron. By varying input wavelength and field angle, this technique can be utilized to precisely characterize chromatic dispersion and distortion of the optics. Furthermore, because the technique only requires compact opto-mechanical accessories and electronic apparatus, it can be readily carried out on large optical systems in the field.

We develop a method for the calculation of the integrals arising in the diffraction theory of aberrations. This method is developed from in a previous one based in the division of the diffracting aperture in semiperiodic zones, which enabled the exact calculation of the Point-Spread Function of an optical system. By a careful analysis of the integration process and of the properties of the semiperiodic zones, we develop a set of formulae that give an approximate value of the result of the diffraction integrals. This permits to avoid the numerical calculation of the integrals, which is a computationally intensive procedure and enables a substantial reduction of the computation times. The method has been tested on aberration-free optical systems and real optical systems and has shown a good accuracy, although some minor problems require further investigation.

Most imaging systems today include a mosaic detector array in the focal plane. optical designers of astronomical telescopes typically produce a design that yields a superb on-axis aerial image in the focal plane, and detector effects are included only in the analysis of the final system performance. Aplanatic optical designs (corrected for spherical aberration and coma) are widely considered to be superior to non-aplanatic designs. However, there is little merit in an aplanatic design for wide-field applications because one needs to optimize some field-weighted-average measure of resolution over the desired operational field-of-view (OFOV). Furthermore, when used with a mosaic detector array in the focal plane, detector effects eliminate the advantage of the aplanatic design even at small field angles. For wide fields-of-view, the focal plane is frequently despaced to balance field curvature with defocus thus obtaining better overall performance. We will demonstrate that including detector effects in the design process results in a different optimal (non-aplanatic) design for each OFOV that is even superior to an optimally despaced aplanatic design.

Calcium fluoride is a desirable material for optical design of space systems in the ultraviolet, visible, and infrared bands. Modem calcium fluoride materials fabricated for the photolithography industry are highly resistant to space radiation. The wide wavelength band and low dispersion are also desirable properties. Unfortunately, calcium fluoride has a host of significant material property issues which hinder its use in the space environment. Low hardness, susceptibility to thermal and mechanical shock, and large coefficient of thermal expansion present significant challenges during development of opto-mechanical designs. Sandia National Laboratories Monitoring Systems and Technology Center has fielded a calcium fluoride based optical system for use in space. The Sandia design solution is based upon a spring-loaded mount which uses no volatile organic compounds. The theory of the Sandia solution is developed and design rules are presented. The Sandia design solution is illustrated for a specific example. Example design and margin calculations are shown. Finally, lessons learned from our design realization and qualification testing efforts are shared for the benefit of the community.

ne demand for high performance lightweight mirrors has never been greater. The coming years will require lighter and higher performance mirrors and in greater numbers than is currently available. Applications include both ground and space based telescopes, surveillance, navigation, guidance, and tracking and control systems. For instance, the total requirement for US government sponsored systems alone is projected to be greater than 200 m(2)/year(1). Given that the total current global production capacity is on the order of 50 m(2)/year(1), the need and opportunity to rapidly produce high quality optics is readily apparent. Key areas of concern for all these programs are not only the mission critical optical performance metrics, but also the ability to meet the timeline for deployment. As such, any potential reduction in the long lead times for manufactured optical systems and components is critical. The associated improvements with such advancements would lead to reductions in schedule and acquisition cost, as well as increased performance. Trex's patented CVC SiC process is capable of rapidly producing high performance SiC optics for any optical system. This paper will summarize the CVC SiC production process and the current optical performance levels, as well as future areas of work.

The merit function landscape of systems of thin lenses in contact, which are perhaps the simplest possible types of optical systems, shows remarkable regularities. It is easier to understand how the optimization parameter space of these simple systems is divided into basins of attraction for the various local minima if one focuses on the (Morse index 1) saddle points in the landscape rather than on the local minima themselves. The existence and the basic properties of these saddle points can be predicted by thin-lens theory, which is applied on a simplified model of the merit function containing only third-order spherical aberration. The predictions of this simplified model are confirmed by numerical results obtained with a typical merit function based on ray tracing.

Many practical approaches have been developed for computing the point spread function (PSF) of imaging systems and the subject has been extensively studied for many years, since this has been a classical topic in OptiCs-6. In recent times, the exact numerical calculation of the diffraction integrals and, hence, of the PSF of image forming systems has been successfully addressed(7-10). These methods are based on the determination of the critical points and the semi-periodic zones of the integrand on the plane of the aperture, followed by the summation for each of the zones. In the present work we address a comparison between an approximate calculation method based on the classical approach and the cited exact numerical procedures, mainly regarding the required computational effort involved.

The Orbiting Carbon Observatory (OCO) will measure the distribution of total column carbon dioxide in the Earth's atmosphere from an Earth-orbiting satellite. Three high-resolution grating spectrometers measure two CO2 bands centered at 1.61 and 2.06 mum and the oxygen A-band centered at 0.76 mum in the near infrared region of the spectrum. This paper presents the optical design and highlights the critical optical requirements flowed down from the scientific requirements. These requirements necessitate a focal ratio of f/1.9, a spectral resolution of 20,000, and precedence-setting requirements for polarization stability and the instrument line shape function. The solution encompasses three grating spectrometers that are patterned after a simple refractive spectrometer approach consisting of an entrance slit, a two-element collimator, a planar reflection grating, and a two-element camera lens. Each spectrometer shares a common field of view through a single all-reflective telescope. The light is then re-collimated and passed through a relay system, separating the three bands before re-imaging the scene onto each of the spectrometer entrance slits using an all-reflective inverse Newtonian re-imager.

The control systems of the miniature robots are suggested for their motion over internal surfaces inside of the small diameter tubes. The mechanical system information-measuring sensor and control systems are considered. Three versions of the mechanical systems are suggested: electromagnetic, triad wheels and conversion of rotation motion to translation one. The electromagnetic mechanism use push pull tipe method for translation motion realization. Developed schemes in the modules design of control systems were checked experimentally on the robot's prototypes. Some results of the computer simulation illustrate the multilink robot control motion along the internal diameters of the tubes. This work was fulfilled under financial support of the Russian Found of Fundamental researches N 01-01-00913 and in frames of Federal Multi Purpose Scientific and Technical Program of Ministry of Industry, Science and Technologies: "Researches and developments on priority directions of science and technology", "Knowledgeable basic investigations" block, "Basic investigations at the field of physics sciences" part Mechanics.

A practical optical printed circuit board (PCB) was demonstrated, using a waveguide-embedded optical backplane and processing boards. The polymeric waveguide was produced by means of a hot embossing technique then embedded following a conventional lamination processes. The core size of waveguide was 100 x 60 mum(2) (input section), 60 X 60 mum(2) (output section), and the propagation loss of tapered polymeric waveguide was approximately 0.1 dB/cm at 850 nm. We prepared a optical backplane with polymeric waveguide by using conventional multilayer board lamination processes. The transmission power and dimension of the optical backplane was same as those of waveguide before lamination. A metal optical bench was used as a packaging die for the optical devices and the integrated circuit chips in both the transmitter and the receiver processing boards. We used a 1 x 4 850 nm VCSEL array with 2 dBm of output power for the transmitter and a PIN photodiode array for the receiver. We successfully demonstrated 8 Gb/s of data transmission between the transmitter processing board and the optical backplane board.
