We propose a single-shot digital holography for recording multiwavelength and complex amplitude information by using a single monochromatic image sensor. The zeroth-order wave and conjugate image in each wavelength are removed from a recorded single hologram by applying parallel phase-shifting interferometry. Angular multiplexing is utilized to record the complex amplitude of an object wave in each wavelength separately, and no color filter is required. The effectiveness of the proposed technique was experimentally verified.
我们提出了一种单次数字全息术，通过使用单个单色图像传感器记录多波长和复振幅信息。通过应用平行相移干涉术，从记录的单个全息图中去除每个波长中的零阶波和共轭像。利用角度复用技术分别记录每个波长的物波的复振幅，且无需使用彩色滤光片。实验验证了所提出技术的有效性。
