The mosaic technology is one of the fundamental approaches for developing mosaic focal plane arrays (MFPAs) of ultra-high dimension with maximum image conversion efficiency. The parameters of infrared (IR) MFPAs are researched depending on the wavelength of the maximum spectral response of photosensitivity of multilayer structures with quantum wells, the pitch of photosensitive elements, and the format of submodules. A mosaic technology prototype with a reduced size of "blind zones" is created based on the fundamental aspects of the development of ultra-high dimensional mosaic MFPAs. Here the...
