  • Distance measuring device
    Patent number: 4905009
    Abstract: A distance measuring device transmits a continuous alternating wave from a wave source to a target which reflects it back toward the device. The wave source is activated until such time that a detector associated with the device senses the beginning of the reflected wave at which time the wave source is deactivated. The wave source is deactivated during the time that the reflected wave is sensed by the detector and upon the sensing of the end of the reflected wave, the wave source is again activated. The frequency at which the wave source is alternately activated and deactivated is a measure of the distance between the measuring device and the target.

  • Adaptive optical system with synchronous detection of wavefront phase
    Patent number: 4865454
    Abstract: An adaptive optical system with local wavefront sensing and control interferometrically determines wavefront phase aberration in an incoming electromagnetic beam and adjusts the reflective surface of a deformable mirror. The system is characterized by wavefront phase sensing local to the deformable mirror and detection apparatus which synchronously detects phase differences between an interferometrically modulated beam and a uniform modulator.

  • Extendable large aperture phased array mirror system
    Patent number: 4825062
    Abstract: An extendable large aperture phased array mirror system includes a plurality of mirror segments cooperatively configured to receive an incoming electromagnetic beam. In response to signals from a sensor indicative of wavefront distortion in the beam, a control apparatus displaces a plurality of segment actuators to configure the mirror segments to generate an outgoing conjugate phase electromagnetic beam.
