Abstract: An image processing apparatus and method for measuring spatial and spectral information from an image of a printed substrate. The image processing apparatus processes the spatial and spectral information from the same acquired image using first and second processors. One of the first or second processors includes a large format sensor and the other of the first or second processors includes a small format sensor. Both the first and second processors are capable of processing both the spatial and spectral information and neither the first or second processor is necessarily dedicated to processing only the spatial or spectral information.

Abstract: The present invention relates to spectral analysis systems and methods for determining physical and chemical properties of a sample by measuring the optical characteristics of light emitted from the sample. In one embodiment, a probe head for use with a spectrometer includes a reflector for illuminating a sample volume disposed circumferentially about the light source of the probe head. In another embodiment, a probe head includes an optical blocking element for forcing the optical path between the light source and an optical pick-up optically connected to the spectrometer into the sample. The probe head also includes a reference shutter for selectively blocking light emitted from the sample from reaching the optical pick-up to facilitate calibration of the spectrometer.

Abstract: A spectrophotometer measures the color properties of a sample by illuminating the sample with a light source. One or more light beams are sensed by an active pixel diode array where each of the beams are sensed by a different array of diodes in the active pixel sensor. Each of the diode arrays are formed on the same substrate by a CMOS process such that each diode array is automatically aligned to each other during formation. Subsequent mechanical alignment is, thus, eliminated.

Abstract: A spectrophotometer which is highly manufacturable at minimum cost nevertheless provides precision of measurement of spectra components of light which is projected therein by maintaining precise optical alignment of optical and electrical components thereof. These components are mounted in a module which is contained in a housing having an entrance aperture which defines an object area for light the spectrum of which is measured by a photodetector in the module at an image area. The module has a base plate provided by a printed circuit board on which a closed wall encompasses an area (a corral) on one side of the circuit board. The wall is a one piece structure which extends to the vicinity of the edge of the board. It is assembled with the board as a unitary structure so that the assembly is made torsionally rigid and resists bending in the plane of the board. The module may be of sufficiently small size so as to be located in a housing which is hand held, thereby providing a hand-held spectrophotometer.

Abstract: Apparatus for color measurements according to the C.I.E. system comprises a first fiber optic cable for receiving and linearizing light from a light source, a lens system for spectrally displaying the linearized light and focusing the light on one end of a trifurcated fiber optic assembly that integrates and separates the light according to the three C.I.E. tristimulus functions. The separated light is received by three photodiodes and electronically evaluated to determine the magnitude of the light corresponding to the tristimulus functions. The fiber optic assembly is made by forming, at one end, a bundle of optic fibers to match the contours of one of the tristimulus functions, encapsulating that bundle, adding a second bundle that, together with the first bundle, will match the contours of the first plus one other tristimulus function, encapsulating that second bundle, then adding a third bundle which together with the first and second bundles, has contours matching the sum of all three tristimulus functions. At the other end of the assembly the three bundles are separated and aligned with their respective photodiodes.

Abstract: A colorimeter provides compensation for changes in the color signature of an object due to lamp aging, stand off distance and view angle changes. The colorimeter senses and stores values indicative of a sample object. In use, the colorimeter senses and creates values indicative of an object. The colorimeter includes a processor which then creates an average ratio wherein the stored values and corresponding sensed values are placed in a ratio, all of the ratios are then summed, and the total is divided by the number of values. Finally, the processor compares the sensed values with corresponding stored values, wherein one of the two values is adjusted by the average ratio.

Abstract: A portable colorimeter for characterizing the optical properties of a colored surface and in particular a colored surface containing metallic or pearlescent particles, which employs three multiangular spectrophotometric measurements to derive color constants for the surface. The colorimeter is a compact integrated unit housing irradiation, detection, control, analysis and display means and employs three illumination angles, preferably -30.degree., 0.degree., and 65.degree., and one detection angle, preferably 45.degree., all measured from the sample normal. The method includes determining the tristimulus values of the color of the sample surface from low resolution spectral reflectance data preferably using twelve detector elements.
