Multiple Imaging Produced by a Binary Combined Optical Element
Multiple imaging produced by a binary combined optical element of axis-off type is reported. The element having functions of splitting and focussing is combined with a two-dimensional Damman grating and a Fresnel zone plate. An imaging lens is unnecessarily needed in application. The split arrays are 9×9 and the focus length is 823 mm. When the plane of the frequency spectrum of an object coincides with the plane of the binary combined optical element, we obtain 9 × 9 multiple images of the object on the images is the same as that of the split arrays. The images are clear and uniform. The relative distribution error of the split beam intensity is less than 5%.
