ABSTRACT:
A laser retroreflector array is provided having an array of cat-eye retroreflectors each with an image forming objective through which the laser beam passes and a partial mirror at the focal plane of the image forming objective. By using the cat-eye retroreflectors to reflect the laser beam, the field of view can be angularly limited so that only one retroreflector in the array at a time reflects the laser beam.
