| 摘 要： | 全息成像提供了一种从单一观察点捕捉具有完整三维信息画面的可靠、快捷的方法。本文回顾了近期提出的单通道菲涅耳数字全息光学系统,该系统能获得由非相干光照射的三维实物体的全息图。在这一静态全息技术中,由三维物体反射或发射光,在通过空间光调制器（SLM）后,用数码相机记录。SLM被用作单通道非相干干涉仪的分束器,使来自物体上各点的球面波被分成两束具有不同曲率半径的球面波。所有球面波干涉结果的非相干总和,即可生成被观测物体的三维菲涅耳全息图。在计算机中可再现该全息图,使其三维特征得以呈现。

| Abstract: | Holographic imaging offers a reliable and fast method to capture the complete 3-D information of the scene from a single perspective.We review our recently proposed single-channel optical system for generating digital Fresnel holograms of 3-D real-existing objects illuminated by incoherent light.In this motionless holographic technique,light is reflected,or emitted, from a 3-D object,propagates through a spatial light modulator（SLM）,and is recorded by a digital camera.The SLM is used as a beam-splitter of the single-channel incoherent interferometer,such that each spherical beam originated from each object point is split into two spherical beams with two different curve radiuses.Incoherent sum of the entire interferences between all the couples of spherical beams creates the Fresnel hologram of the observed 3-D object.When this hologram is reconstructed in the computer,the 3D properties of the object are revealed. |
