We present a photorefractive volume holographic processor for recognition of three-dimensional (3D) objects. The templates are recorded by use of a volume hologram in a photorefractive LiNbO(3):Fe crystal located at the Fresnel diffraction region and correlated in real time with a 3D object illuminated by coherent light. Experimental results for recognition of 3D objects are presented and discussed. To the best of our knowledge, this is the first time a photorefractive volume holographic technique for 3D object recognition has been reported.
我们展示了一种用于识别三维(3D)物体的光折变体全息处理器。模板通过位于菲涅耳衍射区域的光折变LiNbO(3):Fe晶体中的体全息图进行记录,并与由相干光照射的3D物体实时相关。给出并讨论了3D物体识别的实验结果。据我们所知,这是首次报道用于3D物体识别的光折变体全息技术。
