MULTI-ZONE SCANNING DEVICE FOR REMOTE RECEIPT OF EARTH IMAGE FROM GEOSTATIONARY ORBITS Russian patent published in 2006 - IPC G03B37/00 

FIELD: technology for operative hydro-meteorological monitoring by receiving images of full Earth disk from geostationary orbits.

SUBSTANCE: device simultaneously generates N+1 image in optical and infrared ranges of spectrum. Device has two independent information channels. First information channel for forming an image in infrared range of spectrum has two-coordinate scanning mirror, receiving optical system, system of interference filters, N focusing lens systems and N multi-element infrared radiation receivers. Receiving optical system is made in accordance to Galilean telescopic schematic and consists of spherical mirror and lens system. Second independent information channel for forming an image in range 0,4-1,2 micrometers has second scanning mirror, two identical optical systems. Optical systems have lens objective, two rotary flat mirrors and multi-element radiation receiver. Multi-element radiation receivers are mounted in common plane. Sensitive elements lie on the same line. The last element of first receiver corresponds to first element of second one.

EFFECT: decreased filming time down to 1-2 minutes, while simultaneously decreasing mass and dimension characteristics, improved photo-metric precision and reliability, possible broad application of progressive element base.
