| 英文摘要 | an approximate method for generating computer-generated holograms (cgh) of a 3d object with six times faster speed than the conventional algorithm is presented. in the conventional algorithm, a 3d object is sliced into many layers and treated as a collection of self-illuminated point light source. the propagation process of a light ray from every point of an object to all the points on the hologram plane is simulated and interfered with by the reference beam to form a cgh. in our proposed method, under the assumption that the depth of a 3d object is much smaller than the recording distance, we just need to calculate the oblique distance between the first layer and the hologram plane, and then the oblique distances from the other layers to the hologram plane can be obtained from a simple relation, thus the computational time is much reduced. the cgh is optically reconstructed and the quality of the reconstructed image agrees well with that from the conventional algorithm. |
