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.
Claims25
An optical arrangement, comprising:
- a position sensitive optical detector;
- a collimated optical source;
- and a processor configured to monitor the inclination of an object;
- wherein said collimated optical source being configured to transmit a single collimated beam towards said object,
- said position sensitive optical detector being configured to detect the specific location of incidence of an optical signal received from said object, said position sensitive optical detector being received within an enclosure and being optically communicable with said object through an aperture defined by said enclosure, said aperture being configured to restrict reception of scattered light from said object,
- said processor being configured to generate information relating to the inclination of said object from processing the optical signal received at said position sensitive optical detector.
