Reflectance vs temperature measurements on thermochromic Cu(2)HgI(4) show phase transition hysteresis, which forms the basis for recording applications. Long term reflectance relaxation at room temperature has been noted, together with the ability to

As new IR focal plane array (IRFPA) technologies become available, improved methods for coping with array errors must be developed. Traditional methods of nonuniformity correction using simple calibration mode are not adequate to compensate for the i

Infrared holography at 10.6 μm has been accomplished by using a thermochromic material, cuprous mercuric iodide, to record an on‐axis interference pattern. The pattern is subsequently reduced in a two‐step photographic process, and reconstructio
