OPTOELECTRONIC SENSOR OF ANGULAR POSITION Russian patent published in 2009 - IPC G01B11/26 

FIELD: instrument making.

SUBSTANCE: optoelectronic sensor of angular position includes an intermittent light source, a photo-detector, made from nano-graphite film and two pairs of electrodes, and a device for processing electric signals, obtained from the mentioned electrodes. A thin coat of transparent wetting liquid with electrical conductivity far less than the nano-graphite film is applied on it. The liquid coat is hermetically sealed with a transparent lid, closely fitted to the liquid surface.

EFFECT: increase in the range of measured angles by the optoelectronic sensor of angular position.
