SPECTROGRAPH WITH A HOLOGRAPHIC LENS AS DISPERSING/FOCUCING ELEMENT
使用全息透镜作色散和聚焦元件的摄谱仪器

It is possible to construct a simple, compact spectrograph with a single off-axis hologra-fic lens which serves as dispersing and focucing element. In this paper, an optimum construction geometry is presented, the performance of this spectrograph is evaluated. Finally, the experimental results obtained from a prototype of such kind of spectrograph are given.
