Adam Kozma, Anthony Vander Lugt, Andrew M Bardos: Optical information storage system. Harris Corporation, December 13, 1977: US04063226 (50 worldwide citation)

A wideband holographic information storage system records Fourier holograms on film in rapid succession, each hologram storing 128 bits of data. The hologram fringe pattern is held stationary by varying the reference beam frequency to track the variations of frequency of the signal beam that are cau ...

A wavelength division multiplexed fiber-optic communication system employs a pair of terminal stations, at opposite ends of the fiber-optic link, with the base configuration of each terminal station being the same. In each station a selective coupling arrangement is provided between the source or tr ...

Andrew M Bardos: Phase-insensitive hologram readout technique. Harris Corporation, Craig & Antonelli, March 17, 1981: US04256362 (16 worldwide citation)

A hologram-containing storage medium is rapidly scanned or swept by a sinusoidal spatial fringe pattern, the spatial frequency of which varies with time. This may be achieved by the use of a suitable light beam deflection system and frequency shift arrangement disposed up-stream of a focussing lens. ...

Andrew M Bardos, Jon E Holmes, Edward Tegge: Dual feedback path linearization of current modulated laser with dual amplifier circuit. Harris Corporation, Charles E Wands, March 22, 1994: US05296695 (4 worldwide citation)

A laser driver mechanism for image reproduction maintains linear operation over a wide frequency an dynamic range of amplitude-modulated input signals by means of a first feedback loop and a second feedback loop. The second feedback loop contains a first amplifier coupled to receive the input signal ...
