Computer generated hologram (CGH) and it s application in null testing of φ1560 mm hyperboloidal primary mirror
A new method for calculating and drawing the computer generated hologram (CGH) -the fringe order method has been suggested. A OGH with λ/20 accuracy for reconstructed wave-front has been made using this method. The results and effect of OGH null testing of φ1560mm primary mirror in it s early, middle and final polishing stages are given.
