title: Pulsed laser beam control by hot spot tracking.
abstract: The use of a self-developed body-centered reference for precision pulsed laser hot spot tracking is examined through a numerical computer simulation based on a solution of the heat equation with time varying input flux. Tracking resolution and sensitivity in two commonly used infrared sensor bands are compared. To cope with inherent instability, a simple compensation scheme is suggested with a demonstrated improvement in boresight error drift. Optimum performance is obtainable by judicious selection of sensor wavelength bands and sampling times relative to laser pulse time.
