A ballistic optical scanner stopped and reversed by a current impulse at each extreme of scan motion, and accomplishing each direction of scan motion via momentum from the drive impulses has been shown to be a feasible means of achieving equal observation times per scan resolution element. Operation from 0 to or - 34 deg mirror angle from 2 to 10 Hz has been shown to be feasible. Operation through this angle from 0 to 2 Hz in a servo mode, with the scanner displacement slaved to a triangular or other voltage waveform has also been shown feasible. This scanner, of 20 cm clear aperture at 45 deg incidence, has a versatility of control enabling a ballistic search mode to be stopped anywhere within one resolution element of scan 12 mrad mirror angle, where the position may be locked, or where target tracking may then be accomplished by the servo mode of control. The use of two independent mirrors will permit a raster scan having a 3 deg by 3 deg field angle.
