In order to improve the computational efficiency of computer generated hologram(CGH),a novel algorithm was proposed to obtain multiple-type reconstruction images of CGH based on spectrum diffraction theory.The reconstruction images can be rotated,sheared and inversed by just transforming the coordinates of the Fourier spectrum so that the calculation amount is reduced a lot.Besides,it was also validated in experiments.The experiment results prove the new algorithm is feasible.
