| Summary: | 碩士 === 國防大學中正理工學院 === 應用物理研究所 === 94 === In this thesis, two types of optical element made by optical holography technique are presented. These two holographic optical elements (HOEs), one is the holographic reflective volume grating and the other is the transmission volume grating, can be assembled into the head-mounted display (HMD) and the sighting device system, respectively, using both common characteristics of angle- and wavelength- selectivity of the holographic volume grating. There are two main contributions of this thesis. In first part: we propose an idea of changing the recording materials in the holographic recording for producing higher diffraction efficiency HOE-combiner to improve the second generation of HMD developed in our laboratory. The combiner of the second generation HMD was replaced by holographic combiner and integrated into the new opto-mechanical structure design of HMD to overcome the shortcomings that the image of geometrical formation interfered easily by the miscellaneous astigmatic rays from outdoors, and to achieve the goal of delicacy for reducing the fabrication expense and enhancing the image quality. The accomplished HMD not only can be used to observe scenery from outdoors and read the information integrated GPS and digital map in real time for promoting the processing speeds of action. In the second part: we have utilized a 3D design software to construct the layout of sighting device combining a high diffraction efficiency transmission hologram and a collimated green laser module. The accomplished transmission holographic sight combined on the firearms not only offer the firing in the short-range battlefield but also can attain the fast reaction to shoot with unfailing accuracy and promote the survival rate in the battlefield.
