本文介绍一种新型棱镜分光系统,它应用变束棱镜角色散放大分光的原理,它比传统三棱镜分光的色散和分辨率高10～10~2倍。当用这种变束镜成对地组成分光系统时,在分光过程中,出射光与入射光方向间的偏转角保持不变。

This paper reports a new type of prism spectro-system, which, is comparable to the grating. The adgular dispersion amplification of VBP (Variable Beam Prisms) is applied to this spoctro-system, so that its dispersion and resolution are greater than that of normal prism spectro-system by 10-102times. When the VBP is pair-wise set into a apectrosystem, the derivation between the incident and exit beams is always fixed in operation.
