This paper is devoted to the analysis of the optical performance of movable-beam grating structures with both lateral and vertical displacement of the beams. We show that in the vector- diffraction domain one can design high-efficiency switches (e.g. between beam transmitter and beamsplitter mode) and modulators for polarized radiation. The devices exhibit a good tolerance to fabrication and mounting errors and a functional flexibility. In addition, by simulating the optical performance of polysilicon micro-electro-mechanical grating structures at a visible wavelength, reported in the literature, we demonstrate that our tools for rigorous electromagnetic simulation of grating structures work well in the scalar-diffraction domain.

2,3-dimercaptoethylthiopropanethiol (B-thiol), 2,2,2'-dimercaptoethyl sulfide dimethacrylate (MESDMA), and 2-phenylthioethyl thiomethacrylate (MEPSMA) were prepared, which structures were confirmed by IR and (HNMR)-H-1 spectroscopy. A series of homopolymer resin (such as, B-thiol/MDI) and copolymer resin (such as MESDMA/St (25 similar to 50%), and MESDMA/St/MEPSMA) were further prepared, which optical and mechanical properties were much better than thoes of the ordinary resins. The studies and development of such optical resins would be expected to meet the need of optical resin markets.

A critical component in the 2-mu m coherent spaced-based lidar system (SPARCLE) is the compact,off;axis, 25-cm aperture telescope. The stressing optical performance demanded from this telescope coupled with the difficulty associated with aligning such a fast, off-axis system;has created the need for a multiple-axis alignment stage for the secondary minor. Precision micrometer kinematic mounts were used in the laboratory to demonstrate the ability to successfully align the telescope. For the flight configuration, a more robust and considerably smaller stage (both in size and weight) had to be designed in order to fit within the space shuttle packaging constraints. The new stage operates with multiple degrees of freedom of motion to achieve micrometer precision alignment and then uses a mechanical multiple point support to lock-in the alignment and provide stability. The optomechanical design of the flight stage is described.

In the process of designing a control actuator for a. vibration cancellation system demonstration on a large, precision optical testbed, it was discovered that the support struts on which the control actuators attach could not be disassembled. This led to the development of a Linear Precision ACTuator (LPACT) with a novel two piece design which could be clamped around the strut in-situ. The design requirements, LPACT characteristics, and LPACT test results are fully described and contrasted with other earlier LPACT designs. Cancellation system performance results are presented for a 3 tone disturbance case. Excellent results, on the order of 40 dB of attenuation per tone (down to the noise floor on two disturbances), are achieved using an Adaptive Neural Controller (ANC).

Over the past twenty years numerous papers and patents have reported on the design of infrared zoom lenses for a variety of civilian and military applications. The vast majority of these lenses have been afocal 8-12 mu m zoom lenses with magnification ratios of five to twenty. With the advancement of 3-5 mu m staring focal plane array technology a growing demand has emerged for a compact imaging 3-5 mu m zoom lens. To meet this demand a variety of such zoom lenses have been designed which support image formats of over 10 mm diagonal. In this paper the preliminary design of a high magnification 3-5 mu m zoom lens is described. Infrared system modeling, detailed lens performance and manufacturing issues are reviewed.

A novel laser Doppler linear encoder system (LDLE) has been developed at the Advanced Photon Source, Argonne National Laboratory A self-aligning 3-D multiple-reflection optical design was used for the laser Doppler displacement meter (LDDM) to extend the encoder system resolution. The encoder is compact [about 70 mm(H) x 100 mm(W) x 250 mm(L)] and it has sub-Angstrom resolution 100 mm/sec measuring speed, and 300 mm measuring range. Because the new device affords higher resolution, as compared with commercial laser interferometer systems, and yet cost less, it will have good potential for use in scientific and industrial applications.

A Finite-Difference Method in Non-Orthogonal Curvilinear Coordinate System (FDM-NOCCS) is the combination of the domain transformation technique and the Finite-Difference Method (FDM). It has the visualization and simplification of the traditional FDM. On the other hand. it overcomes the weakness of EDM in dealing with complicated boundary shapes, averts the interpolation between the grid points in the vicinities of boundaries, and also avoids the abnormalism in the transformation from the physical domain to the computational domain. The FDM-NOCCS is used in the computer aided design of electron gun for color cathode ray tube. Compared with the formal FDM, the FDM-NOCCS can save quite a lot of CPU time and computer memory. FDM-NOCCS works well with the complicated e-gun systems design.

This paper is directed at the analysis of the basic operating principles, design, operation, and performance of a different type of optical modulator, capable of large phase modulation through the change of the optical index of refraction. This is achieved by modification of waveguide boundary conditions by incorporating quantum wells that can be charged or emptied of electrons at the planar dielectric waveguide boundaries, by application of gate voltages. Such an unconventional way of achieving the desired modifications in the optical refractive index will provide attractive alternative and more versatility than the conventional means of realizing such modifications, such as electrooptical effects (electroabsorption, Franz-Keldysh effect, optical birefringence), carrier induced effects (band filling, band gap renormalization), and free carrier absorption (plasma effect). Furthermore, the technology (e.g. molecular beam epitaxy, metalorganic chemical vapor deposition, ion beam etching, and other micro machining techniques) of fabrication of these new devices is already in place, so the proposed concept can be tested to facilitate further development. Based on these projections, we propose a planar-based dielectric waveguide having confined electrons in quantum wells at the boundaries. Microstructure devices made from semiconductors, e.g. CoSi2 or GaAs/Ga1-xAlxAs, are the most practically fabricated in the form of planar structures. Moreover, it is well adapted for various gate electrode geometries for activation and control of the quantum wells.

The objective of this research program was the development of the technology for the industrial manufacturing of HOEs for technical applications such as: holographic solar concentrators for utilization in photovoltaic energy conversion and solar photochemistry, and integrated holographic stacks for daylighting, glazing and shading in buildings. Some of the fabricated HOEs exhibit apertures in the order of 8 square meters. The accomplished technology facilitates the continuous fabrication of the holographic films on glass or plastic substrata. The standard holographic material we use for the fabrication of HOEs is dichromated gelatin (DCG) on glass or plastic film (PET) substrata The dichromated gelatin layer could be prepared with different compositions to accommodate the desired exposures and chemical processing procedures. At present we manufacture holographic plates on glass substrata in sizes of up to 1 meter square. The holographic film on plastic substratum is 20 cm wide and could be made in lengths of hundredths of meters. The inexpensive fabrication of such large formats is attained by automation of the entire process: film manufacturing, hologram copying, development and test. We present in this paper the design considerations and the developed manufacturing procedures. These comprise the fabrication of large format reflective holograms for concentrating mirrors and the copying of transmissive holograms, such as gratings and lenses, using in-plane contact copying in checkerboard arrangement or rotating drum continuous copying onto an endless plastic film.

Conference on current developments in optical design and engineering Vii

A new design of diffractive superresolution elements with surface-relief phase screen has been presented to improve the quality of the superresolved diffractive patterns. The diffractive phase screens have been designed by our proposed global optimization method, called Global/Local United Search Algorithm. The new algorithm combines the global exploration properties of Genetic/Annealing algorithms and the accurate exploitation power of the "hill-climbing" method, resulting in the characteristics of fast convergence, global search capability, and high performance diffractive patterns. The designed diffractive phase screens can improve the performance of the superresolved diffractive patterns from the view of Strehl ratio, reduction of the focal spot, and control of the sidelobe intensity. The results show that the diffractive phase screen can produce much small spot size and great lower sidelobe intensity while keeping an acceptable Strehl ratio, which has important applications in high density data storage.
