摘要
用白光源再现一狭缝离轴全息图,得到色散的狭缝象;在狭缝实象处加一狭缝光阑,实现了单色输出。计算并测量了谱线半宽度,结果表明单色仪是可行的。
A dispersive slit image is obtained when a white light source is used to reconstruct a slit off-axis hologram. By fixing a slit aperture at thelocation of the image, monochromatic light is obtained,and the half width of spectrum is caculated and measured. The results show that the new type of monochrometer can be used.
