Investigation of Aircraft Canopies by Moire Mapping
The project involves various aspects of moire techniques applied to aircraft canopies, eye surface, etc. A graduate student and two research associates, Dr. Wong and Dr. Pearson, worked together on experiments and development of software that is able to automatically analyze the moire patterns. The first version of the software made automated analysis of deflectograms possible; however, this version still requires many improvements. Recently, new contacts were made with both Tinker Air Force Base and Nordam Company, Tulsa. Both centers are very interested in the moire technique for aircraft canopies quality control. Samples have been received for analysis; the system for analysis of canopies is ready, and preliminary deflectograms have been made.

WilTel Fiber Optics
This research was devoted to four areas, the first of which was the modeling of a fiber loop optical-optical switch. The work involved introduction of higher order cross terms for ultra fast pulse interaction analysis. Some work was also done on attempts to correct for third order dispersion and Raman self frequency shifting by the introduction of frequency dependent gain. The second area involves improvements on the optical parametric oscillator system. The work involved optimization of the driving Ti-Sapphire laser by the selection of the optimum output coupling as well as selection of operating conditions for the LiBO crystal. Currently, researchers are working to modify the operating conditions of the optical parametric oscillator (OPO) towards non-degenerate arrangement. The third area concerns efforts to construct a practical version of the polarization independent, all fiber optical circulator. A collaboration began with Dr. Edward Knobbe to produce highly efficient Faraday fibers using solgel technology. A white paper has been submitted to the Rome Lab of the Griffiss Air Force Base. Finally, investigations are being made into anneal fiber splices being built. The purpose of the system is to strengthen fusion splices between optical fibers. Researchers expect to start the first tests soon.

A System for Characterization of the Mottle Level of Colored Plastic Films
The effort was devoted to design of a defect detection system for slowly changing transmission of optical "mottle" films. A graduate student worked on the project at a quarter time load. A prototype optical system has been built and final results have been obtained. The system is very simple. Researchers use a linear Charge-Coupled Device (CCD) array, which measures spatial distribution of the transmission with error of less than 0.1%. The system can measure plastic films of arbitrary width. The results have been transferred to 3M for application on its production lines.
