Testing optical surface with phase recovery

  • Using the angular spectrum theory of scalar diffraction, the phase retrieval algorithm with two intensity patterns was carried out, and was used to test the optical surfaces and wavefronts. The wavefronts of the spherical wave surfaces were retrieved by the algorithm in experiment. The algorithm of wavefront fitting based on the Zernike polynomials was realized with computer programmer by calculating generalized inverse matrix of Zernike coefficients.
