Abstract

In optical interference measurement, the standard wave provided by the standard optical flat owing to the influence of manufacturing processes, affects seriously on the improvement of the accuracy of the test. To solve this problem, a method brings forward based on the computer-generated hologram to achieve the reconstruction of the standard wave-front; Secondly, on the basis of the mathematical model of standard wave-front reconstruction, the required wave-front is reconstructed in use of the different coding to encode wave-front hologram and MATLAB; Finally, the different coding techniques for standard wave-front have been compared. The results show that the theory based on the standard computer-generated hologram wave-front reconstruction algorithm can achieve the standard wave-front reconstruction.
