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 21):
An apparatus for decoding at least one user data from at least one data encoded laser beam having plurality of orthogonal aberration modes in an optical communication system, wherein said user data being indicative of amplitudes of said orthogonal aberration modes, said apparatus comprising:\n at least one wavefront sensor adapted to:\n receive, said data encoded laser beam as one or more input laser beams from a transmitting unit communicably coupled with said apparatus; \n detect, presence of aberration in said input laser beams; \n generate, at least first and second sensor output signals, in the case of the modal wavefront sensor, or only one aberration sensor output signal in the case of the zonal wavefront sensor, corresponding to each input laser beam, \n transmit, said first and second sensor output signals or sensor output signal, to a data processing unit for subsequent processing; \n wherein, said data processing unit, operably coupled to said wavefront sensor, is configured to:\n determine amplitudes of said orthogonal aberration modes, using, the difference between said first and second aberration sensor output signals or said aberration sensor output signal; \n decode said user data, using said amplitudes of said orthogonal aberration modes.
