The one-shot phase-shifting digital holography using phase difference of orthogonal polarizations is proposed. Using a CCD camera with pixelated polarizers, three images for phase analysis can be obtained simultaneously. The proposed method can be applied to a moving object, because a complex field of the wavefront of a 3D object can be obtained in a single exposure.
A method to design an input phase mask for double-random phase-encoding optical encryption is proposed. The input phase mask is iteratively designed so that the extent of the Fourier spectrum of the product of an input image and the input phase mask correspond to the space bandwidth of the optical system. By using the designed input phase mask, we show that the bit-error rate is improved. We also discuss the number of phase levels of the designed input phase mask.
The quasi one-shot phase-shifting digital holography using phase difference of orthogonal polarizations is proposed.
The use of orthogonal polarizations can make it possible to record two phase-shifted holograms simultaneously. By combining the holograms with distributions of a reference wave and an object wave, the complex field of the wavefront of a 3D object can be obtained. As two phase-shifted holograms can be obtained simultaneously in the proposed method, even a moving object can be recorded.
