  • Method of monitoring coalignment of a sighting or surveillance sensor suite
    Patent number: 5786889
    Abstract: A method of monitoring the coalignment of a sighting or surveillance sensor suite including a coaligned laser (18) and sensor (12) includes the steps of: modifying the beam from the laser (18) to render it visible to the sensor (12); and redirecting the modified beam from the laser (18) to impinge on the sensor (12). In the preferred embodiments the frequency of the beam is doubled by a doubling crystal. For certain lasers this renders the beam visible to the human eye, or to a camera.
