Variable Acuity Display Development. Volume II. Infrared Lens Feasibility Study

The feasibility of designing a nonlinear lens capable of operating with second generation infrared monolithic focal plane detector arrays has been established. The feasibility was based on a computer performance model which evaluated the effect of 3 to 5 micron or 8 to 14 micron infrared imaging spectrum, the number of scan lines, F/number, lens blur, and scanner type. In addition, the effects of narcissus were determined which resulted in requirements on lens element location. The results indicate that such a lens could be built and should operate in the 8 to 14 micron spectral region. It would have an 8 inch clear aperature and would have resolution and field-of-view adequate to support human vision. In addition, it could be constructed with state-of-art techniques and materials.
