SCANNING DEVICE Russian patent published in 1994 - IPC

FIELD: infrared image production. SUBSTANCE: device has mirror objectives mounted to enable revolution around common center, immovable radiation receiver and plane mirror fixed rigidly at an angle to the plane of revolution of objectives between the objective installed opposite input aperture and revolution center of objectives. Plane mirror is provided with rectangular aperture, and radiation receiver is fixed opposite this aperture behind the mirror outside the radiation beam coming from objective of survey. Radiation beam shielding with cryostat body is eliminated as a result when operating cooled radiation receiver that enables to operate both non- cooled and cooled radiation receivers. EFFECT: wider operating opportunities of the scanning device with keeping up high image quality. 3 dwg
