| Abstract: | Experimental results are shown of optically reconstructed images from computer-generated holograms made with only binary-quantized levels in the real parts of the Fourier-transform complex disturbance of a signal and displayed by a line printer. Relatively good images having no distortion due to the high-pass filtering effect are reconstructed from computer generated holograms multiplied by the random phase factor. Reconstruction is also possible from the present holograms for signals having various degrees of light intensity. |
