Research output: Contribution to journalArticlepeer-review


Using computer-generated holograms (CGH) to test unsymmetrical "petal" phase plate is suggested. The expression of the aberration for the "petal" phase during propagation is analyzed and deduced, and the results of the optical design for the "petal" surface test system are listed. The separation of the diffraction orders and the binary process of the continuous CGH phase function are discussed and the sample of the amplitude CGH is given. The minimum line spacing of the CGH is 40μm and its effect on the wavefront error is only 0.005 λ. The tolerance analysis of the testing system is carried out, and the total effect from all alignment tolerances that affect testing system is 104.293 nm.
