OPTICAL-ELECTRONIC DEVICE FOR OBTAINING COORDINATE AND NON-COORDINATE INFORMATION ON POINT OBJECTS Russian patent published in 2009 - IPC G01B11/26 G02B23/00 

FIELD: physics; optics.

SUBSTANCE: optical-electronic device is designed for obtaining information on rotation of point objects from intensity fluctuation of one polarisation component of received solar radiation scattered by the objects and their coordinates. The device has a cowling, an objective lens of a telescopic system, a reflector, a first polariser with a V-shaped plate, an eyepiece of the telescopic system, a second polariser, condenser and an optical radiation receiver. The device also contains a semi-transparent mirror, placed between the objective of the telescopic system and the first polariser under Brewster angle such that, the polarised component of solar radiation scattered by the object and reflected by the semi-transparent mirror is received by the additional photodetector, connected to an analyser of photoinduced current fluctuation.

EFFECT: determination of parametres of rotation of an object based on analysis of intensity fluctuation of one polarised component of received radiation with determination of coordinates of the point objects.
