ABSTRACT:
A spectral analyzer and direction indicator system (10) is disclosed and includes first and second optical channels (20,30) for providing detected optical information indicative of incidence direction and spectral content of incident radiation. The first optical channel includes a reflector element (11) having a non-ruled section (11a) and a spectrally dispersing ruled section (11b); an analytical optical system (13); and a detector array (15). In the reflector element of the first optical channel the non-ruled section is tilted relative to the ruled section. The second optical channel includes a non-dispersing reflector element (17), an analytical optical system (19), and a detector array (21).
