A sensor system for determining the spatial location of radiation relative to the sensor including three unit sensors each having a cylindrical optical lens and a linear array of photosensitive elements positioned in the focal plane at a fixed angle with respect to the longitudinal axis of the lens.

A sensor system for determining the spatial location of radiation relative to the sensor including three unit sensors each having a cylindrical optical lens and a linear array of photosensitive elements positioned in the focal plane at a fixed angle with respect to the longitudinal axis of the lens. Each lens determines substantially a plane of radiation passing through the source. The unit sensors are arranged to define three separate planes having the radiation source being detected as common point. The detected signals are processed to identify respectively the serial position of the elements activated by the focused radiation. Ancillary calculating means calculates the location of the source from the serial position information. By detecting a plurality of sources coupled to a movable body, the present invention enables the user to continuously determine the direction of a fixed axis of the movable body.
