【発明の名称】スペクトル分析方向指示装置
Document Type and Number:
Japanese Patent JPS61502909
Kind Code:
A
Abstract:
A spectral analyzer and direction indicator and direction indicator (10,20) is disclosed and includes reflection gratings (13,15,25,27,37,39), associated optical systems (17,19,29,33,41,45) and associated detectors (21,23,31,35,43,47,30). The reflection gratings (13,15,25,27,37,39) are arranged to provided angles of diffraction which are utilized to determine spectral content and incidence direction of collimated or essentially collimated incident radiation.
