Patent Number: 7,733,506

Title: Optical tilt monitoring apparatus

Abstract: An optical arrangement includes a position sensitive optical detector, a collimated optical source, and a processor configured to monitor the inclination of an object. The collimated optical source is configured to transmit a collimated beam towards the object. The position sensitive optical detector is configured to detect the specific location of incidence of an optical signal received from the object, and the processor is configured to generate information relating to the inclination of the object from processing optical signals received at the position sensitive optical detector.
