ELECTRO-OPTICAL COMPLEXED WATCHING AND IDENTIFYING SYSTEM FOR UV, VISIBLE AND IR SPECTRUM RANGES Russian patent published in 2007 - IPC G02B23/06 G02B17/08 

FIELD: optical engineering.

SUBSTANCE: system has identification channel and detection channel. Identification channel has two-mirror objective in form of ring-shaped segment of main mirror with convex spherical surface and of aplanatic corrector, identification channel radiation receiver. Detection channel has objective disposed in cone-shaped hollow area formed by radiation flux, which radiation is received by objective of identification channel, and detection channel radiation receiver. Whole structure is placed inside spherical envelope, which envelope carries simultaneously the surface of ring-shaped area of aplanatic corrector, protection window, which window has to be fairing with area of transparency of 0,0235-3 mcm, and device for fixing radiation receivers of detection and identification channels. Wide-angled UV variable objective is used as objective of detection channel with area of transparency of 0,235-0,4 mcm. Objective is brought into coincidence through mirror, mounted at angle at back section, with radiation receiver is form of silicon array radiation receiver. Either silicon array being sensitive up to wavelengths λ=1,1 mcm, or image intensifier being sensitive up to wavelengths λ=1,8 mcm or CCD array being sensitive within IR spectrum range is used in narrow field channel as radiation receiver.

EFFECT: longer range finding; complete elimination of parallax for any channel at simultaneous operation of both channels.
