Abstract
Holographic Night Vision Goggles (HNVG) are unique in the world; they have been developed by the belgian company OIP for the specific needs of the Belgian Army. With respect to classical night vision goggles, HNVG feature the big advantage of a permanent image which is either a (green) intensified image (provided by a MCP image intensifier) or a (pink coloured) see-through image depending on the level of ambient illuminance. This unique feature of a permanent image is entirely due to the incorporation of Holographic Optical Elements (HOEs) which are in fact holographic mirrors. Unfortunately, those HOEs impose additional severe requirements, e.g., a maximum distortion of 7.5 % in order to avoid "holographic drunkenness". It is the aim of the present paper to justify these additional requirements and to deal with the measurement methods of the most important parameters of the HNVG as they are written in the specifications of the Belgian Army.
