Abstract :
Application of a receiving device on basis InAs, for a thermovision microscopy is studied. The device designed and made in an ISP of the Siberian Branch of the Russian Academy of Science, fundamental parameters: dimensionality 128×128, a step 50 microns, a range of lengths of waves 2.5-3 microns. For decrease of a background radiation from warm parts of a case of the device it is offered to use a spherical mirror. The radius and a position of a mirror are calculated so that the matrix of a receiving device "saw" only cold (that is - not radiating) parts of a cryostat. Tests have shown its sufficient effectiveness. The background radiation has decreased in 15 times. It has allowed increasing integration time in 9 times and a temperature solution in 8 times. The spatial solution which has made 7 microns is measured. Mathematical handling allows improving this value up to ∼ 4 microns.
