Abstract: The invention provides spectroscopic systems and spectrometers employing an optical interference filter module having a plurality of bandpass regions. In certain embodiments, the systems include a mechanism for wavelength tuning/scanning and wavelength band decoding based on an angular motion of one or more filters. A spectral processing algorithm separates the multiplexed wavelength-scanned bandpass regions and quantifies the concentrations of the analyzed chemical and/or biological species. The spectroscopic system allows for compact, multi-compound analysis, employing a single-element detector for maximum performance-to-cost ratio. The spectroscopic system also allows for high-sensitivity measurement and robust interference compensation.

Abstract: An optical emission spectroscopic (OES) instrument includes a spectrometer, a processor and an adjustable mask controlled by the processor. The adjustable mask defines a portion of an analytical gap imaged by the spectrometer. The instrument automatically adjusts the size and position of an opening in the mask, so the spectrometer images an optimal portion of plasma formed in the analytical gap, thereby improving signal and noise characteristics of the instrument, without requiring tedious and time-consuming manual adjustment of the mask during manufacture or use.

Abstract: A sensor system for remote object detection, tracking, characterization, and discrimination can have a plurality of sensors. A shared optical train that can facilitate blending of information from the sensors, so as to provide a single view for the plurality of sensors. Small and/or dim objects can be more readily detected. High-resolution 3 dimensional space object imagery and on-demand target information gathering can be provided with reduced data latency. The undesirable effects of atmospheric turbulence along the aiming direction can be mitigated even when there is a high relative velocity between the surveillance platform and remote target.
