Abstract: A laser beam steering module includes an optics assembly that directs a first portion of a laser beam through an output aperture and a second portion of through a sensing path. The optics assembly adjusts a position of the laser beam through the output aperture and sensing path responsive to position control signals. A sensor array in the sensing path receives the second portion of the laser beam and in response thereto generates electrical beam position signals indicating a position of laser beam through the output aperature. The electrical beam position signals have values that are a function of a temperature of the sensor array and are used in generating the position control signals to adjust the position of the laser beam as a function of the values of the electrical beam position signals. A thermal stabilization circuit stabilizes the temperature of the sensor array responsive to thermal control signals.

Abstract: A method for transitioning a target from a missile warning system to a fine tracking system in a directional countermeasures system includes capturing at least one image within a field of view of the missile warning system. The method further includes identifying a threat from the captured image or images and identifying features surrounding the threat. These features are registered with the threat and image within a field of view of the fine tracking system is captured. The registered features are used to identify a location of a threat within this captured image.
