多天体摄谱技术的现状述评

A Review of the Present Status for Multi-object Spectroscopy

本文介绍对比了物端棱镜,非物端光栅、棱镜光栅、透棱栅、多孔缩焦器光谱仪,长缝摄谱仪、多缝摄谱仪,光纤引导多天体光谱仪等多天体摄谱仪的发展过程、现状和优缺点。最后提出了准三维摄谱仪的一些可能性和优点。

In this paper, after a general review about different kinds of multi-object spectro-scopy technology such as objective prism, grating in converging beam, grism, grens, multi-hole focal reducer spectrograph, long slit spectrograph multi-slit spectrograph and fiber linking spectrograph,we suggest a new idea about the quasi-three-dimensional spectrograph and discuss its possible advantages,
