We present a distortion-tolerant 3-D object recognition system using single exposure on-axis digital holography. In contrast to distortion-tolerant 3-D object recognition employing conventional phase shifting scheme which requires multiple exposures, our proposed method requires only one single digital hologram to be synthesized and used for distortion-tolerant 3-D object recognition. A benefit of the single exposure based on-axis approach is enhanced practicality of digital holography for distortion-tolerant 3-D object recognition in terms of its simplicity and high tolerance to external scene parameters such as moving targets. This paper shows experimentally, that single exposure on-axis digital holography is capable of providing a distortion-tolerant 3-D object recognition capability.
我们展示了一种使用单次曝光同轴数字全息术的抗畸变三维物体识别系统。与采用传统相移方案（需要多次曝光）的抗畸变三维物体识别不同，我们提出的方法仅需合成一张数字全息图，并用于抗畸变三维物体识别。基于单次曝光的同轴方法的一个优点是，就其简单性和对诸如移动目标等外部场景参数的高耐受性而言，增强了数字全息术用于抗畸变三维物体识别的实用性。本文通过实验表明，单次曝光同轴数字全息术能够提供抗畸变三维物体识别能力。
