23. A method comprising:
-
projecting cross dispersed light onto a micro mirror array having a plurality of individual mirrors; activating individual mirrors following a selective sequence of mirror combinations to direct an individual wavelength or individual wavelengths to a sample; detecting a signal reflected by the sample for each mirror combination; and recovering a complete spectrum by recombining data from signals according to the collection sequence in use.
