Abstract
A sensor for determining the lateral position and direction of an optical source having an arbitrary spatial intensity distribution. The sensor includes two substantially separated apertures which establish the extent of an optical radiation ray bundle which includes rays from the optical source. The power centroid of this optical radiation ray bundle is measured in the plane of the first aperture and in the plane of the second aperture. Optical source position and direction are computed from these two measurements.
