Binocular Night Vision Helmet Holographic Combiner Design And Research

Modern war on the demand of high-tech is more and more. HMD as a good human-computer communication device to be widely used in modern war, especially in recent years the use of holographic display to raise the combat capability and viability.Holographic combination is a key component of the holographic display, it solved the problems of coating mix for the low rate of transmission and the low rate of reflective. At the same time, it also there are some Shortcomings, such as: complex to Production, high demands on the environment, difficult to save. This paper from the theory, applications layered media film theory analysis the holographic combination, the establishment of a reliable mathematical models and computer programs prepared MATLAB, analyzed the impact of portfolio diffraction efficiency for the various parameters, after the optimal mix of different, Determined to achieve the design goals of the corresponding records of medium thickness and wavelength, and other parameters; dichromated gelatin, while a relatively good production holographic optical elements of the recording material, but it speeds poor, especially the little red light sensitive, so the choice of topics in the methylene blue (MB) of the red-sensitized dichromated gelatin (MBDCG) as a record of materials, to join a four-guanidine (TMG) as an electronic donor, at the same time the article analysis of the principle of exposure. In subsequent the papers summed up the influence of various factors in the process of he holographic combination's production and exposure, determined the parameters and detail process of production that to meet the design's objectives. Finally, this paper analyzed the impact to diffraction efficiency because of the surface shape and surface grating, the results of the analysis for the production of holographic combination provides a theoretical and experimental basis, have a high value.
