Abstract:
A single-shot astigmatic phase retrieval wavefront sensor system (100) includes a single 2-dimensional (2D) grating (110) configured to split an incoming optical beam (112) into plural split beams (114-I) and to modulate each of the plural split beams (114-I) with a corresponding modulation of plural modulations; a light sensor (120) configured to receive the plural split beams (114-I) and determine a light intensity of each of the plural split beams (114-I); and a processing unit (130) connected to the light sensor (120) and configured to calculate a phase distribution of a wavefront of the incoming optical beam (112) based on simultaneously measured light intensities of the plural split beams (114-I).
