ABSTRACT:
The present invention relates to spectroscopic methods and systems for collecting electromagnetic radiation from an object using a continuously-spinning wavelength-selecting (CSWS) device, e.g., an interference filter(s) or grating. One embodiment of the invention provides a spectroscopic system for collecting electromagnetic radiation from a target. The spectroscopic system has at least one beam of electromagnetic radiation that interacts with the target. The system includes a continuously spinning wavelength-selecting (CSWS) device, e.g., a continuously spinning interference filter/grating driven by a DC motor, in the path of the at least one beam. The device filters the radiation with regard to wavelength to produce filtered radiation. The system further includes at least one detector in the path of the at least one beam for detecting the filtered radiation.
