Since the dichromated gelatin has a higher diffraction efficiency in all holographic recording materials, the aim of this research is to use dichromated gelatin as the recording material and to make use of the principle of holography to design holographic optical components, especially in fabrication procedure of dichromated gelatin film and in experimental technique to form a high diffraction efficiency using different angular exposure method
為了產生優質的聚焦能力與效率,本研究採用目前具有最高繞射效率( 80 ~ 90 % )的重
鉻酸明膠材料作為感光劑,除了自行調制藥劑比例成分,並依嚴格的製作步製成重
鉻酸明膠全像片外,並採用不同角度重覆曝光方式改良干涉式波
帶板無法自動追蹤的缺點,經過多次試驗與改進,藉以形成具備高繞射效率和自動追蹤功能的全像光學波
