The demand for single-shot and common-path holographic systems has become increasingly important in recent years, as such systems offer various advantages compared to their counterparts. Single-shot holographic systems, for example, reduce computational complexity as only a single hologram with the object information required to process, making them more suitable for the investigation of dynamic events; and common-path holographic systems are less vibration-sensitive, compact, inexpensive, and high in temporal phase stability. We have developed a single-shot common-path off-axis digital holographic setup based on a beam splitter and pinhole. In this paper, we present a concise review of the proposed digital holographic system for several applications, including the quantitative phase imaging to investigate the morphological and quantitative parameters, as a metrological tool for testing of micro-optics, industrial inspection and measurement, and sound field imaging and visualization.
近年来，对单次曝光和共光路全息系统的需求变得越来越重要，因为此类系统与其他同类系统相比具有多种优势。例如，单次曝光全息系统降低了计算复杂度，因为只需处理包含物体信息的单个全息图，这使得它们更适合用于动态事件的研究；而共光路全息系统对振动的敏感度较低，结构紧凑、成本低廉且具有较高的时间相位稳定性。我们基于分束器和针孔开发了一种单次曝光共光路离轴数字全息装置。在本文中，我们简要介绍了所提出的数字全息系统在多种应用中的情况，包括用于研究形态和定量参数的定量相位成像、作为微光学测试的计量工具、工业检测与测量以及声场成像与可视化。
