Abstract: Color detection apparatus wherein only light that has been diffuse-reflected, and has not been mirror-reflected, from the object whose color is to be detected is processed. Light from a source passes through a first polarizer before the light is incident on the object whose color is to be detected. Light reflected from this target object passes through a second polarizer which blocks all mirror-reflected light while permitting a portion of the diffuse-reflected light to pass. After passing through the second polarizer a portion of the light is directed onto a color filter after which the intensity of the transmitted light is detected. The intensity of the portion of light not applied to the color filter is also detected. The ratio of the output of the two detectors is a function of the color of the reflected light. The principal axis of the light incident on the target object is coincident with the principal axis of the reflected light that is to be processed, thus eliminating the need to accurately position the target object.

Abstract: A narrow angle, narrow bandwidth optical receiver system for detecting light rays reflected from a predetermined area illuminated by a laser beam having a known wavelength. A large collecting lens having a small field of view receives incoming reflected rays which are collimated by a pair of relay lenses having a narrow bandwidth, triple cavity, single element interference filter positoned therebetween. The filtered rays are processed by a photomultiplier tube and a CRT display to illustrate signals of interest within the illuminated area. An alternate embodiment provides a cone element to receive filtered rays from relay lenses for decreasing the size of the receiver system.

Abstract: An automatic test instrument for gaging the percentage of various constituents in organic substances by comparing the reflective optical density of the subject at various wavelengths. Narrow band optical filters are connected together in the form of a rotatable paddle wheel positioned so that the filters can be individually swept through the incident light path between the specimen and wideband light source. As the filter wheel turns, the band of light passed by each filter is progressively shifted with the changing angle of the filter relative to the light path. The filter wheel configuration includes opaque vanes extending from the ends of the filters to periodically interrupt the passage of light to the specimen. Photocells are positioned to sense the level of light reflected from the specimen. The output of the photocells is sampled at predetermined times relative to the rotation of the filter wheel to yield values indicative of reflected intensity at certain wavelengths. Using these values, an electronic circuit in one embodiment calculates three optical density difference values corresponding to moisture, protein and oil content of the specimen. The difference values are automatically inserted in three linear equations which are solved to obtain readings representing the true percentages of oil, water and protein contained in the specimen. Each time a new specimen is loaded for testing, the instrument is automatically calibrated against a standard sample, preferably Teflon (Trademark). The output of the photocells is amplified in a special circuit which subtracts the level of dark period current from the output when the photocells are illuminated.

Abstract: An opto-electrical measuring apparatus for determining the hemoglobin content of an illuminated hemoglobin solution arranged in the path of light between a light source and a photoelectric transducer by evaluating the light absorption of the solution within a predetermined wavelength range. The spectral or spectrum properties of the light source, the transducer and other components arranged in the path of the light emanating from the light source are accommodated or matched to one another such that in the absence of the hemoglobin solution in the path of light an electrical magnitude generated in the photoelectric transducer possesses a spectral dependency which in the wavelength range of 540 to 560 nm constitutes a maximum value and to both sides of such range with a half-value width of at least 60 nm continually decreases to less than 20% of the maximum value at about 500 and 600 nm, respectively, and externally of these band limits asymptotically approaches the value null.

Abstract: A color balance adjusting device for color printing or enlarging is exposed to the light traversing the printer variable density color filters and the color negative and includes a photocell and red, green and blue filters selectively movable into registry with the photocell or three photocells whose incident light traverses respective red, green and blue filters. The output signals from the photocell or photocells are amplified through respective amplifier circuits whose output is connected to an electrical meter, at least two of the amplifier circuits having members for adjusting their gains. Another light measuring device employing the same meter is employed for measuring the total light traversing the color negative. A standard negative is inserted in the printer and the amplifier gains are adjusted for two of the spectral ranges until the meter in each case provides a predetermined reading, and the standard negative is replaced by a negative to be printed without disturbing the amplifier gains and the neutral density filters associated with the compensating filters are adjusted to achieve the predetermined meter readings.
