Paper Abstract

A real-time optoelectronic measurement system is proposed to measure the wavefront distortions of scanning beams of a phased-array laser radar. This measurement system includes electric control rotating and translating platforms and a cyclic radial shearing interferometer(CRSI). CRSI is an effective interferometry to mesure the laser wavefront. A inversion algorithm is used to precisely reconstruct wavefront phase distribution from interferograms generated by the CRSI. An actual experiment of laser wavefront distortion measurement is implemented successfully. The experimental results show that this optoelectromic measurement system can measure laser wavefront distortion of a phased-array laser radar in accuracy and in real time.
