ABSTRACT:
The laser source energy and the target source energy goes through a common ptical path to a beam splitter. The energy from the target source is filtered, allowing only the laser information to pass through to the laser quadrant detector. The second path from the beam splitter has a blocking filter to block the laser energy, and the remaining energy, that of the target source, is measured by the target quadrant detector. The geometric translator is a computer controlled azimuth and elevation gymbal device which tracks (drivers to null) the target source. The target source is a strobe lamp. The angular information from the dual quadrant detectors and the geometic translator are fed into an compact mini-computer.
