Abstract
Spectral analyzer and direction indicator systems (10,20,30,40,50) are disclosed and include optical elements (11,17,27b,33b,35b,39b) for providing optical information which depend on incidence direction and spectral content, and further includes optical elements (23,27a,33a,35a,39a) for providing non-diffracted optical information which depend on incidence direction. The respective optical information as detected by detector arrays (15,21,25,31,37) are utilized together to provide information for specifically identifying spectral content and incidence direction of collimated or nearly collimated radiation.
