<p>Apparatus for monitoring, converting and calibrating the spectra displayed by a colored object (14), using wavelength dispersion provided by a variable wavelength filter (17). The apparatus may serve as a spectrophotometer, as a colorimeter, or as a spectroradiometer or other device that monitors and calibrates a light signal by decomposition of the signal into a wavelength distribution. The apparatus may also be used as part of a feedback network to monitor and correct colors displayed by a color monitor (61), color printer (63), color scanner (65) or other similar peripheral device controlled by a computer (56) that is part of the network. <IMAGE></p> |
