Abstract:
1. A spectroscopic system for collecting electromagnetic radiation from a target, the spectroscopic system comprising: a source of a primary beam of electromagnetic radiation; a continuously spinning wavelength-selecting device in the path of the primary beam, the device operative to pass only a restricted spectral band of the electromagnetic radiation to produce filtered radiation, the device comprising a beamsplitter in the path of the primary beam and operative to split the primary beam into a first subordinate beam and a second subordinate beam; a target cell in the path of the first subordinate beam, the target cell adapted to interact with a portion of the filtered radiation to produce filtered target radiation; and a reference cell in the path of the second subordinate beam adapted to interact with a portion of the filtered radiation to produce filtered reference radiation; a first detector in the path of the first subordinate beam and operative to detect the filtered target radiation and to produce detected target radiation information; a second detector in the path of the second subordinate beam and operative to detect the filtered reference radiation and to produce detected reference radiation information; and a processing device in communication with the first and second detectors and operative to process the detected target radiation information and the detected reference radiation information and to produce processed target information.
