Abstract
A color measuring sensor assembly includes an optical filter such as a linear variable filter, an optical detector array positioned directly opposite from the optical filter a predetermined distance, and a coherent fiber faceplate having a plurality of optical fibers interposed between the optical filter and the detector array. A light beam propagating through the fiber faceplate from the optical filter to the detector array projects an upright, noninverted image of the optical filter onto a photosensitive surface of the detector array. Each optical fiber in the fiber faceplate is of limited aperture to control the tendency of light to diverge and to increase the resolution capabilities of the sensor assembly. The color measuring sensor assembly can be incorporated with other components into a spectrometer device such as a portable calorimeter having a compact and rugged construction.
