WAVEFRONT COMPENSATION IN OPTICAL SYNTHETIC APERTURE IMAGING PROCESSORS

摘要

There is provided a System and method of wavefront compensation in a synthetic aperture imaging system. A return signal data représentative of a signal reflected by a target area to be imaged is received. A compensation phase figure corresponding to a wavefront compensation to be applied is provided. The compensation phase figure is added or otherwise applied to the phase pattern of the return signal data in order to obtain a compensated phase pattern. An optical beam is spatially modulated according to the compensated phase pattern to produce a modulated optical beam such that the compensation phase figure produces a wavefront compensation on the optical beam. An image of the target area is optically generated using the modulated optical beam.
