Foveal Lens Feasibility Study, 8 to 14 Micron Spectral Region.
Abstract
This study proves feasibility and establishes preliminary design for a nonlinear lens capable of imaging in the 8-14 micron spectral region. When coupled to existing linear infrared scanners this lens can fully support human vision in both field of view (160 deg) and resolution (1 cycle/milliradian). This capability is achieved through optical distortion which causes focal length to vary by a ratio of 50/1 from an axis (2 inches) to 80 deg field angles (.04 inch). The lens has an F number of two and a clear aperture of eight inches in diameter. (Author)
