Abstract: A spectroscopy system having enhanced noise reduction that comprises (i) an arc lamp light source of emitted light, which emitted light is projected as an image of the light source; (ii) a slit aperture through which the emitted light is projected; and (iii) a detector operably associated with the slit aperture for detecting the emitted light. The slit aperture, the arc lamp, and the image of the arc lamp each have a major axis. The major axis of the slit aperture is oriented essentially orthogonally to the major axis of the image of the arc lamp, so that the signal-to-noise ratio of the spectroscopy system is improved as compared to the signal-to-noise ratio of the spectroscopy system when the major axis of the slit aperture is oriented essentially parallel to the major axis of the image of the arc lamp.

Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin2(m&thgr;+p&pgr;/4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by correspond filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.
