conference on current developments in Lens design and optical engineering II

There are some unique optical design considerations in the design of a distributed aperture telescope array consisting of a number of individual afocal collector telescopes and a single combining telescope. As might be expected, diffraction limited imagery over the field of view requires the correction of spherical aberration, coma, astigmatism and field curvature. However, there is an additional requirement on the design of the collectors. Coherent addition of the light from the collectors requires that the ratio of the sine of the input and output chief ray angles be essentially constant over the field of view. This output angle restriction is equivalent to requiring the collector telescopes to have a specific variation in angular magnification with field. Variation of magnification with field is, by definition, image distortion. With simple two and three mirror afocal collector telescope designs, there are insufficient design degrees of freedom to control distortion in addition to the other aberrations. In this paper, we present a modification to a three-mirror collector design that permits the image distortion to be adjusted in a controlled manner without influencing the other third order, Seidel aberrations. This modification permits a large distributed aperture telescope array to be designed that has both a simple optical form and a much larger phased (i.e. corrected) Field of view. As a design example, we investigate the effect of the distortion correcting element on the size of the achievable field of view for a 45 meter diameter distributed aperture telescope array populated with 8 meter diameter collectors.

The Chemical Imaging System (CIS) is a small, high-speed long-wave infrared (8 - 12 mum) imaging spectrometer which is currently under development by the United States Army. The fielded system will operate at 360 scans per second with a large format focal-plane-array. The CIS, which is currently at the exploratory development stage, is scheduled for transition to engineering development in 2005. currently, the CIS uses the TurboFT FTS in conjunction with a 16-pixel direct-wired HgCdTe detector array. The TurboFT spectrometer provides high-speed operation in a small, lightweight package. In parallel to the hardware developments an algorithm and software development effort is underway to address some unique features of the CIS. The TurboFT-based system requires a non-uniform sampling Fourier transform algorithm in order to preserve signal fidelity. Also, the availability of multiple pixels can be exploited in order to improve the interference suppression capabilities of the system by allowing the detection and identification algorithm to adapt its parameters to the changing background. Due to the enormous amount of data generated, the signal processing must proceed at very high rate. High-speed computers operating with a parallel architecture are required to process the data in real time. This paper describes the current CIS "bread box" system. It includes some field measurement results followed by a discussion of the issues and challenges associated with meeting the design goals set for the program.

We describe the operating principle, design and test results for the high-power semiconductor switch which based on the assembly of reverse switched dinistors (RSD). This switch has the following operating parameters: operating voltage - 25kV, peak operating current - up to 200kA, maximum transferred charge - up to 70C. The switch is intended for use by pulse power systems of Nd-glass lasers. The features of switch modes at such banks are discussed.

In Free Gyroscopic Stabilized Seekers, the Primary Minor has the multiple functions of a magnetic rotor, the primary rotating mass and the primary reflector for the optical train. The introduction of rare-earth magnetic alloys to this class of seeker has provided increased flexibility in materials selection, opto-mechanical design and cost of manufacture. Along with superior magnetic properties, the rare-earth alloy Neodymium-Iron-Boron (NdFeB) comes with the undesirable properties of anisotropic CTE, high susceptibility to corrosion and manufacturing challenges. This paper discusses the opto-mechanical design, structural and optical modeling and analysis of a primary mirror assembly utilizing an NdFeB insert with centrifugal, linear acceleration and thermal loading as well as the optical test results, qualification testing of long-term figure stability and validation of the mechanical/magnetic/optical design model.

Eyepieces are a part of visual optical systems. Because of their wide field of view and long eye-relief, it is difficult to further improve the existing eyepieces using all-refractive surfaces. Since diffractive elements demonstrate unique characteristics: negative dispersion and non-field curvature, the eyepiece design can be improved by using refractive-diffractive hybrid surfaces. In this paper, several design examples using refractive-diffractive hybrid surfaces to design moderate field of view (FOV) eyepieces were studied. Firstly, a design example using a diffractive surface to replace the negative piece in the cement doublet of a conventional Kellner type eyepiece is presented. Then a design example is given by employing two diffractive elements to replace the negative elements used in the conventional symmetrical eyepiece. For the above examples the eyepiece aberration correction techniques were also analyzed.

A segmented array of mirrors was designed for a solar concentrator test stand at MSFC for firing solar thermal propulsion engines. The 144 mirrors each have a spherical surface to approximate a parabolic concentrator when combined into the entire 17-foot diameter array. The mirror segments are aluminum hexagons that had the surface diamond turned and quartz coated. The array focuses sunlight reflected from a heliostat to a 4 inch diameter spot containing 8 kilowatts of power at the 15 foot focal point. The derivation of the surface figure for the respective mirror elements is shown. The alignment process of the array is discussed and test results of the system's performance are given.

A strategy for optimizing both the on-axis and the off-axis performance of coherently (directly) coupled visual instruments is presented. The strategy draws on the recently published body of data regarding the influence of various individual Seidel aberration and aberration combinations on subjective contrast sensitivity and resolution tasks, as well as studies on the correlation between subjective image quality and objective instrumental figures of merit. An MTF-based metric allows both optimization and tolerancing to be performed in a coherent manner that is based on experimental results of the effects of aberrations.

In this paper, we present an optical design of a near-infrared (at FeI 15648.5 Angstrom) birefringent filter system which is used to obtain the chromatic images of the sun and measure the solar magnetic field at the Big Bear Solar Observatory (BBSO). This system consists of a prefilter, a liquid crystal analyzer, a wavelength-tunable birefringent filter and a Fabry-Perot Etalon. This system is expected to achieve a clean narrow pass band (1/8 Angstrom). It can also be tuned across the spectral line to obtain line profiles of two-dimensional fields of view. During the design of the tunable near-IR birefringent filter and the test of its components, we found the value of birefringence index mu (n(e) - n(o)) of calcite at spectral range near 15648.5 Angstrom is very different from the value in literature(1). Because the birefringence index is important for the design of birefringent optical components, the birefringence index of calcite and its thermal coefficient are measured. Some test results of the four pairs of calcite prate used in the birefringent filter are presented.

The Tropospheric Emission Spectrometer (TES) is one of the instruments slated to fly on the EOS Aura satellite in 2003. TES is a Fourier transform spectrometer designed to measure the concentration of various tropospheric chemical species. The Focal Plane Opto-Mechanical Assemblies (FPOMAs) are situated at the end of the TES optical train and are comprised of cryogenic telescopes, reimaging optics, and focal planes. We present the cryogenic optical design of the FPOMA units and discuss optimization parameters and predicted performance. We present measured performance data and compare it with the predicted performance.
