用Refractive Index相位匹配法研究HDG-棱镜色散体系（GRISM）的组成和光谱特性
Study of the Composition and Spectral Characteristics of a HDG-Prism Disperse System (GRISM) by Refractive Index Phase Matching
摘要：
研究了用卤化物蒸汽处理卤化银乳剂制成的折射率调制型HDG与棱镜折射率匹配的GRISM的组成和特性。GRISM在湿度或紫外线暴露等外部影响下保持稳定。用空间频率为600 mm ~（-1）的HDG的GRISM获得的汞原子光谱显示出波长差为2.1nm的黄色双谱线，两条谱线充分分离。
英文摘要：
The composition and characteristics of a GRISM gained by refractive index matching between a refractive index modulation type HDG and a prism is investigated, the HDG being built by processing silver halide emulsion with halide vapor. The GRISM has been stable under external influences like humidity or ultraviolet light exposure. The mercury atomic spectrum obtained by a GRISM based on a HDG with a spatial frequency of 600mm-1 shows yellow dual lines with the wavelength difference of 2.1nm sufficiently separated.
