Abstract: A spectrophotometer utilizes a band-pass filter array for splitting incident light into a plurality of light components of different wavelengths, a plurality of silicon photodiodes for receiving the respective light components, and a memory for storing spectral sensitivity information. The spectral sensitivity information is obtained by integrating the spectral sensitivities of spectrodetectors relative to each sectionalized wavelength regions sectionally generated from a measurement wavelength region. Each of the spectrodetectors include a band-pass filter array and a silicon photodiode in combination. A central processing unit calculates simultaneous equations representing the relation between the output from each of the silicon photodiodes, the spectral sensitivity information stored in memory and the light intensity of the sectionalized wavelength region, to obtain the light intensity.

A transmission optics assembly (618) is adapted to measure transmission density of light rays projected through the object sample when the object sample is in the form of a film control strip. A motor assembly (426) operating with a drive wheel assembly (434) and idler wheel assembly (440) automatically moves the object sample (588, 620) through the apparatus (410) adjacent the source light (580). A pair of guides (468, 470) are selectively adjustable by the operator to control movement of the object sample (588, 620) through the apparatus (410). In response to input from a key switch assembly (492) activatable by the operator, the apparatus (410) is adapted to perform various color density measurement and calibration functions, and display appropriate information to the operator through the use of a visual display (490).

Abstract: A spectrophotometer is operative to measure or analyze the colors of materials such as textiles. A test sample is held by a holder and is illuminated by polychromatic light. Diffuse light reflected from the sample is collected and converted to variable monochromatic light and detected. The system is calibrated by using a secondary white standard calibrated against a primary white standard, by using a black standard to compensate for dark current and internal reflectance from a pressure plate, and by using a mirror to obtain internal wall reflectance used in a correction factor.

Abstract: A sensing head assembly for a multi-color printing press on-line densitometer movably mounted on support members that extend across the width of a printed web of paper that has printed thereon, in addition to the printed matter being monitored, a plurality of spaced-apart color bars that extend across the width of the paper at predetermined intervals along its length. During operation, the sensing head assembly is traversed back and forth across the width of the material in a manner such that a sensing head assembly views a selected color bar at different points along the width and length of the printed web of material. At least two high luminance lamps are mounted within the sensing head housing for projecting light through a window onto a specimen plane of the material being printed to thereby define an inspection zone for illuminating a single selected color bar at any point along the width and length of the printed material. A receptor objective lens having a maximum numerical aperture views the area of the printed material passing through the inspection zone and illuminated by the high luminance lamps and projecting an image plane through an aperture plate that is located in a position just below the best focused color bar image. The aperture plate has a respective aperture opening for each discrete elemental color area comprising the color bar and high impedance semiconductor light sensitive photodetector cells are positioned to allow a respective elemental color light passing through the respective aperture openings to impinge on their light sensitive surface. If desired, respective complimentary color filter elements may be positioned intermediate the aperture openings and the photodetectors.

Abstract: A color analyzer for measuring a color synthesized by the additive mixture of primary colors, each having an arbitrary but constant relative spectral energy distribution. The color analyzer has a light receiving portion consisting of three or more photoelectric transducer elements equal in number to said primary colors and having independent spectral sensitivities, so as to generate electric quantities representing the received optical energy levels, and an electric calculating circuit for generating electric outputs representing the energy levels of said primary colors individually, independently and simultaneously. The color analyzer can also measure the luminance of the light source, and display CIE chromaticity.
