Abstract:
1. An imaging spectrometer system sequentially comprising: a source (LS) of electromagnetic radiation; a collecting means (L a stage (STG) for supporting a sample (S); a first focusing means (L a first digital light processor (DLP); and a second focusing means (L said imaging system further optionally comprising polarization state generation and polarization state analysis means between said source of electromagnetic radiation and said sample, and after said sample, respectively; said first digital light processor (DLP) comprising an array of a multiplicity of microscopic mirrors (MM), each said microscopic mirror (MM) being controllable to reflect incident electromagnetic radiation along at least two different loci; said collecting means, first focusing means and second focusing means all being selected from the group consisting of: such that in use said source (LS) of electromagnetic radiation provides an expanding beam (BI) of electromagnetic radiation to said collecting means (L at least one of said microscopic mirrors (MM) in said first digital light processor (DLP) being caused to be oriented to direct electromagnetic radiation incident thereupon to said second focusing means (L said imaging system further comprising, after said first digital light processor (DLP), a spectrometer sequentially comprising: such that said dispersing means (G) receives electromagnetic radiation from said first digital light processor (DLP) which is directed in said desired direction, and directs it to said dispersing means (G) which provides electromagnetic radiation to said second digital light processor (DLP
