This paper provides an overview of the development of closed-form Green's functions in planar multilayered structures, with an emphasis given to the discrete complex image method (DCIM). In addition to the review of the materials in the literature, the latest developments on DCIM and its applications to artificial materials are also discussed.
We describe the design, fabrication, and performance of a class of simple handheld fluorometers. The devices consist of a sensor along with an integrated optical filter packaged in a handheld format. The sensor is a d...

An optically passive athermal infrared optical system working in the 8 - 12 micron long wavelength infrared band was designed by using a special infrared optical material AMTIR (amorphous material transmitting infrared radiation). The design principle, design results are described in this paper. In addition, the optical system was incorporated with an infrared focal plane array forming an infrared camera. The thermal test of imaging quality of this camera is also presented

This paper discusses some methodologies that apply to the opticaldesign of reflective wide-field cameras. Among the methods considered are off-axis and eccentric pupil systems, concatenation of systems, tilted component systems, aberration theory, and confocal systems. The goal of the paper is to review design methods. In particular some systems are shown to illustrate two methodologies.

Several common impediments to successful lens design can be removed by application of new techniques. These involve using information that has long been calculated during the design process, but then discarded. Problems so addressed include the nuisance of discovering ray failures in the starting configuration, and that of tolerance desensitization, among others.

Automated computer-aided procedure for component selection, opticaldesign, and optimization was developed and used to produce prototype ocular optics of a head-mounted display for biomedical imaging, with the field of view and resolution approaching those of normal human vision. The new display has the potential to dramatically increase the amount and fidelity of real-time visual information presented to the user. The selected approach was based on a tiled configuration and "optically stitched" virtual image, resulting in seamless imagery generated by multiple micro-displays. Several optical configurations were studied in the design stage, to arrive at the optimal optical layout. The automated procedure provided for extensive search of the best candidate stock components out of thousands of candidate lenses offered by different vendors. At each iteration, the candidate lens was "digitally inserted" in the optical layout, its position was optimized, and the achieved merit function characterizing the quality of the stitched image was stored, along with the design prescription. A few best designs were then closely evaluated in a traditional "manual" procedure. The design effort was followed by experimental demonstration and tests of a limited prototype optical system.

The diffractive optical element (DOE) is always modeled as an ideal pure diffractive clement which neglects the refractive dispersion of the clement's material. In this paper, a new model of the diffractive optical element is proposed, in which the effect of the refractive dispersion of the DOE's material is considered. The new model is explained and compared with standard diffraction-order expansion with the help of a hybrid system example. The analytical results show that the new model has an important meaning for the exact analysis of the hybrid refractive-diffractive optical system.
