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 30):
A method for generating at least one data encoded laser beam in an optical communication system, said method comprising:\n generating, by a laser generating means in a transmitting unit, at least one incident laser beam; collimating, by two or more collimating lenses, said incident laser beam; incidence, said incident laser beam on at least one light modulator; generating, by at least one hologram provided on said light modulator, at least one order of a diffracted beam carrying a user defined phase profile wherein said diffracted beam includes plurality of orthogonal aberration modes; encoding, by said light modulator, a digital order, which is a shifted ternary number, at least one user data with said diffracted beam of said laser beam at consecutive instants of time; generating, at least one data encoded laser beam, wherein said user data is indicative of amplitudes of said orthogonal aberration modes; transmitting, through an atmospheric or free space optical path or at least two lenses positioned in said atmospheric or free space optical path, said data encoded laser beam to a receiver unit communicably coupled with said transmitting unit.
