An advanced Holographic One-Tube Goggle (HOT Goggle') has been designed for the U.S. Army Research. and Development Commands,' Night Vision and Electro-Optics Laboratory, Fort Belvoir, VA. The goggle is essentially a unit power night-vision, electro-optical sight consisting of an 'objective lens, image intensifier tube (converting visual and near-IR. radiation to visual at 0.5430 p.m), and an eyepiece. The eyepiece portion is of particular interest, as it uses two diffraction optical elements to provide the user with a biocular view of the output of the intensifier tube. Since the goggle is designed for use by ground troops, the physical. requirements are for a lightweight, low-moment unit that is compatible with the infantry helmet and gas mask. Optical requirements include: milliradian resolution, large exit pupils, interpupillary adjustment, large field of view overlap, and low distortion. The use of diffraction optical elements allows the user the unique ability to simultaneously view and superimpose the actual and intensified scenes.
