ABSTRACT:
A system for determining the angles of elevation and azimuth of a source of collimated energy comprises a detector consisting of an annular entrance opening in an opaque structure, and an annular segmented optical detector spaced from and axisymmetric with the opening. Laser, or other collimated light energy passing through the opening illuminates all, or particular portions of the segmented detector depending on the direction and angle of incidence of the energy, thereby providing all of the information necessary to determine the elevation and azimuth of the source of the energy.
