Approximate analysis of dynamics of motion of thermal direction-finder deflector in the anti-scan mode

An approximate theory of the deflector operation in the anti-scanning mode is set forth. Here a goal is pursued to use maximally the frame time for exposure of staring array of photodetector (included in the surveillance wide-band thermal direction finder) owing to the high operating speed of the small-size deflector with a mirror on the rotor and with an electromagnetic moment motor. The potential possibilities are revealed for the two-loop dynamic system with continuous motion of the force loop and with line-of-sight stops at the expense of the deflector that provides the asymmetric oscillations of the line-of-sight, which are in anti-phase with respect to the main loop.
