Multi-Focal Length and Multi-Channel Holographic Optical Element.

Abstract

A new holographic optical element (HOE) consisting of the hololenses with different focal lengths and diffractional channels is described. The object space axes of all hololenses in the HOE are the same, while each optical axis in the image space is different. By the aid of such HOE, the object planes at different distances can be imaged into the corresponding channels. Therefore, a 3-D object field may be displayed by many 2-D images. The primary experimental results for sampling 3-D particles field are presented. (MM)
