Abstract
Light weight and compactness are critical requirements in the design of many optical systems and the use of holographic optics often provides an ideal solution to the size and weight problem. In this paper, the design and fabrication of a wide field-of-view (FOV) holographic lens for use in a laser receiver are described. The holographic lens is designed to image incominlaser radiation at 850nm onto a solid state detector array over a field of view of x (±26.7 in the diagonal direction). Over the limiting aperture, the effective f/number of the holographic lens for each incident angle is f/2.5. Over the entire lens aperture, however, the f/number of the holographic lens is f/0.7 in order to accommodate the 53.4 FOV. Experimental results obtained with the holographic wide FOV laser receiver are presented. The location of the focussed spot can be determined to within one pixel of the detector array, providing the laser receiver with an angular resolution better than 1 mrad.
