摘要： A method is provided for measuring the color of irregular surface materials, including textiles which may provide dissimilar color measurements from different viewing angles, by illuminating a sampling area of the irregular surface material approximately perpendicularly thereto and measuring the color reflected from that area at a substantial angle, preferably about 45 degrees, with a plurality of separate photodetectors arrayed circularly around the illuminated sampling area of irregular surface material to receive the reflected illumination from substantially opposing directions and at a substantial angle to the illuminated area, for providing a more accurate yet lower cost color measurement system for textiles that can be used easily, quickly, and uncritically in terms of the handling, positioning and orientation of the textile material being tested.

摘要： To determine the spectra of objects that have different degrees of fluorescence, a plurality of reference databases are provided, each reference database being suited to a different degree of fluorescence. A most appropriate one of the reference databases is selected based on a predicted degree of fluorescence of an object for which a reflectance spectrum is to be determined. The prediction of the degree of fluorescence may be based on user input, or may be predicted by using a priori information, such as a priori knowledge of media types.

摘要： A developability sensing system with an optical sensor for measuring the density of imaging material samples on an imaging surface of a printer, with an illumination source and photosensor system for measuring the amount of reflected illumination from the imaging materials. A first lens system and its first photosensor may receive both specularly and diffusely reflected illumination from certain imaging materials. A separate lenslet system is positioned outside of the first lens system. It may comprise one to four spaced apart generally cylindrical lenslets with a central axis generally perpendicular to the imaging material sample and an end surface facing the imaging material sample defined by a segment of a hyperbolic curved surface to form a rotationally symmetrical lens with a hyperbolic cross-section. There are separate photosensors for these lenslets, which are positioned and optically adapted to only receive diffusely reflected light from the imaging material sample, even though reflected illumination from the imaging material sample has both specularly and diffusely reflected illumination from partially specularly reflective imaging materials.
