    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.

    Abstract: The invention relates to a procedure for determining an identification of a sample of material, or its properties. Electromagnetic radiation from a radiation source (1) is reflected or transmitted through the sample. The radiation from the sample is collected and analyzed over several channels (7, 7', 7"), which modulate the radiation with a spectral transmission function which is unique for each channel. The modulated radiation is transmitted to one or several detectors (9, 9', 9") which produce output signals which are further electronically processed. The spectral range of each of the individual channels is common to all of the channels. Within the common range the channels are provided with different spectral transmission functions (7, 7',7") which are optimally chosen for a given application.

    Abstract: The invention is a lamp quality judgement apparatus and judgement method which judge quality by detecting the state of gas sealed in an electric lamp such as a gas-filled incandescent lamp, etc. in which gas with an Argon-Nitrogen mixture as its main component is sealed. More particularly, a lamp in which such gas is sealed is classified as a good product or as a bad product by imposing a high DC voltage or a high AC or pulsed voltage with a comparatively low frequency of 1 kHz or less across the lamp's valve and filament coil to produce discharge and emission, in the lamp, of a light in a wavelength region in the vicinity of 560 nm and judging the radiation state in this 560 nm light spectrum, i.e., the state of discharge in the lamp. The means employed for detecting the light spectrum radiation state include means for judging lamp quality by monitoring the temporal response characteristic in the light spectrum in the 560 nm wavelength region and means for effecting accurate judgement of lamps regardless of variations in the state of discharge in lamps by detecting the difference in intensity of the light spectra of two wavelength regions which are the light spectrum of a 560 nm wavelength region and a light spectrum of a wavelength region other than the 560 nm wavelength region.
