Abstract

An apparatus and procedure for the boresight alignment of the transmitter and receiver optical axes of a laser radar system are described. This accurate technique is applicable to both shared and dual aperture systems. A laser autostigmatic cube interferometer (LACI) is utilized to align a paraboloid in autocollimation. The LACI pinhole located at the paraboloid center of curvature becomes the far field receiver track and transmit reference point when illuminated by the transmit beam via a fiber optic pick-off/delay line. Boresight alignment accuracy better than 20 prad is achievable.
