【Abstract】 Phase-shifting holography is proposed to record double-exposured hologram whose reconstructed image is formed by subtraction of two reconstructed wavefronts. It can be used to improve SNR, resolution and contrast of the reconstructed image. In this paper, the theory of this technique is developed and the method of introducing phase-shift is discussed. The experimental result is compared with, that of common in-line and off-axis double-exposure holography.更多还原
