DEVICE TO TAKE BEARING OF OPTICAL RADIATION POINT SOURCE Russian patent published in 2010 - IPC G01S3/78 

FIELD: instrument making.

SUBSTANCE: proposed device comprises optical system and 2n encoding of masks-photo receivers of the Gray binary code system. Said optical system consists of n independent identical optical channels, each comprising wide-angle lens, projection system, encoding mask and radiation receiver. Note here that encoding masks are arranged on common plane-parallel plate and aligned with wide-angle lens focal points, while mask linear focuses are made with correction of distortion of said lenses. Note also that said wide-angle lens of aforesaid channel is made from convexo-plane lens with its plane surface glued to convexo-plane plate aligned with encoding mask. Note here that curvature radii R of convexo-plane and concave-plane lenses are equal.

EFFECT: higher noise immunity, accuracy and validity in taking bearing on optical source.
