Abstract:
The present invention provides a free space optical communication system that uses orthogonal modes of aberration in a laser beam as means for encoding the information. The system comprises a transmission station which transmits the user defined information in terms of the amplitudes of certain orthogonal aberration modes present in the transmitted beam. The beam then travels through free space before it reaches the receiving station. The receiving station comprises a high speed wavefront sensor of light beams. The wavefront sensor measures the amplitudes of various orthogonal aberration modes present in the incident beam at different instants of time. The amplitudes of the orthogonal modes at a certain regular time interval are then used to extract the user information.

Claim (Index 16):
An apparatus for transmitting at least one data encoded laser beam having plurality of orthogonal aberration modes in an optical communication system, said apparatus comprising:\n at least two collimating lenses, to collimate said laser beam; at least one light modulator unit, adapted to:\n receive said laser beam, transmitted by said collimating lenses: \n generate, using one or more hologram/holograms, at least one order of diffracted beam carrying a user defined phase profile; \n modulate, said order of diffracted beam of said laser beam with a digital order of said user data, at two or more consecutive instants of time; \n generate at least one data encoded laser beam and thereby transmit said data encoded laser beam to a receiving unit, wherein said receiving unit is communicably coupled with said apparatus; \n wherein, said user data in said data encoded laser beam is indicative of amplitudes relative to time of said orthogonal aberration modes.
