Abstract: A correlation spectrometer can detect a large number of gaseous compounds, or chemical species, with a species-specific mask wheel. In this mode, the spectrometer is optimized for the direct measurement of individual target compounds. Additionally, the spectrometer can measure the transmission spectrum from a given sample of gas. In this mode, infrared light is passed through a gas sample and the infrared transmission signature of the gasses present is recorded and measured using Hadamard encoding techniques. The spectrometer can detect the transmission or emission spectra in any system where multiple species are present in a generally known volume.

Abstract: Encoded spatio-spectral information processing is performed using a system having a radiation source, wavelength dispersion device and two-dimensional switching array, such as digital micro-mirror array (DMA). In one aspect, spectral components from a sample are dispersed in space and modulated separately by the switching array, each element of which may operate according to a predetermined encoding pattern. The encoded spectral components can then be detected and analyzed. In a different aspect, the switching array can be used to provide a controllable radiation source for illuminating a sample with radiation patterns that have predetermined characteristics and separately encoded components. Various applications are disclosed.

Abstract: A multispectral imaging system (1) and method utilize an optical processor (3) for simultaneously comparing an input wavelength spectrum observed in a single spatial pixel in a scene image from a multispectral imager (2) with a plurality of template wavelength spectra to find a correlation. The optical processor exploits the three-dimensional attributes of optical correlation to perform massively parallel correlation processing by modulating (4) respective ones of a plurality of spectral bands of the input wavelength spectrum of an incident light beam (6) with modulating elements (5) to alter at least one property of the incident light beam by a value corresponding to the observed intensity of the input spectrum in the respective spectral band. In a disclosed embodiment, the modulated beam is expanded and transited through a spatial light modulator (7) having a two-dimensional array of modulating elements. Each row of the elements of the array alter the at least one property of the incident light by values corresponding to a particular template wavelength spectrum of a plurality of template wavelength spectra of the modulator. The values corresponding to each template spectrum are the conjugates of the representative values of the modulating elements of the template spectrum of the plurality of template spectra.
