Abstract
An apparatus and method for producing a spectrally variable radiation source and systems including same is disclosed. An embodiment of a spectrally variable radiation source is disclosed including a broadband radiation source, a collimating element, a dispersive element, an imaging element, an output aperture and an optional output collimating element. An embodiment of a spectrally encoded infrared chromatograph incorporating the inventive spatially variable radiation source is disclosed. An arbitrary spectrum projector for simulating emission or absorption spectra for chemical and biological agents, as well as projecting calibration and test spectra for characterizing sensors is also disclosed.
