摘　　要：详细介绍了二元位相型菲涅尔透镜列阵器件（ＢＰＦＬＡＳ）的设计原理、制作过程和测试方法，研制了２４×２４元８阶ＢＰＦＬＡｓ，对０．８４μｍ波长的焦距为４６．５ｍｍ，单元尺寸为１．５×１．５ｍｍ２，衍射效率达７７．３％．有关应用实验表明，该器件具有平行光分束、多路成像及傅里叶交换功能，在列阵发光器件的光学准直，光学相关器等方面有广泛的应用前景．The design principle, manufacture process and the measllrenlent method for binary phase-only Fresnel lens arrays (BPFI-As) are given. The 24×24 array of BPFLAs with eight discrete phase levels has been made. The size of each individual lenslet is 1. 5×1. 5mm2. For 0. 84μm wavelength, the focal length is 46. 5mm and the diffraction efficiency is over 77. 3%. The experiments show that this device has the functions of beamsplitter, multiple imaging and multiple Fourier transformation. It has vast application prospects in array collimation and optical correlator.
