ABSTRACT:
An optical turret shaped for minimum aerodynamic and aero-optic impact at supersonic speeds. The turret optics includes a common optical element for scanning the optical tracking beam and the projected laser beam to provide for automatic alignment of both beams. Separate windows associated with the tracking beam and the laser output beam is provided for increased efficiency, the window material in each window being compatibel with the optical wavelengths passing therethrough.
