Abstract: A spectrometer (10) includes a two-dimensional array of modulatable micro-mirrors (18), a detector (20), and an analyzer (22). The array of micro-mirrors is positioned for receiving individual radiation components forming a part of an input radiation source. The micro-mirrors are modulated at different modulation rates in order to reflect individual radiation components therefrom at known and different modulation rates. The micro-mirror array combines a number of the reflected individual radiation components and reflects the combined components to the detector. The detector is oriented to receive the combined radiation components reflected from the array and is operable to create an output signal representative thereof. The analyzer is operably coupled with the detector to receive the output signal and to analyze at least some of the individual radiation components making up the combined reflection.
