Abstract: A colorimeter or color measuring device measures color of a sample or an object, and displays measurement value or values according to user defined index or indices, calculated by a user-defined formula. Data of the user-defined formula is read in from outside of the colorimeter and converted into a coded form which can be executed by a controller of the calorimeter. The data of the user-defined formula or the coded data is stored in the colorimeter. Accordingly, the colorimeter has good portability and convenience despite its capability of expressing the colors of various samples or objects by user-defined original index or indices.

Abstract: Percentage concentrations of constituents or color components of a sample are determined using a spectral analyzer with a wide illumination spot size and detector. The analyzer irradiates the sample, picks up diffuse reflectance of individual wavelengths from the sample and spatially separates the diffuse reflectance into a response at individual wavelengths. The result is to simultaneously detect the intensities of the individual wavelengths in parallel from the sample being analyzed. Percentage constituents of a composite substance can be determined or, alternatively, the components of color in a sample can be determined by analyzing wavelengths of reflected light.

Abstract: The present invention relates to a device and a method for determining the quality of surfaces. An illuminating means of a first optical means radiates light at a predetermined angle onto the measurement surface. A second optical means is likewise aligned at a predetermined angle to the measurement surface and a photosensor receives the light reflected from said measurement surface and converts same into an electrical measurement signal which is characteristic of the reflected light. A control and evaluation means comprising a processor and memory means controls the measurement sequence and evaluates the measurement results, which are emitted via an output means. The illuminating means comprises at least one light-emitting diode. The light emitted by said illuminating means is configured such that its spectral characteristic comprises at least blue, green and red spectral components in the visible range of the spectrum. A filter means is provided in the path of radiation between the light source and the photosensor. The evaluating means evaluates the reflected light and derives therefrom a parameter which characterizes the surface.

Abstract: An object recognition system comprises a sensing apparatus for collecting light reflected from objects presented at a point-of-sale machine. The sensing apparatus includes a mechanism, such as a holographic disk or diffraction grating, for separating the color components of the light reflected from the object and directing, the color components onto an optical detector such as a two-dimensional imaging array, or a one-dimensional imaging array or single photo-sensitive optical cell used in conjunction with a rotating mirror. A pattern recognizer compares the spectral response, including the locations, amplitudes and widths of energy peaks of the different color components, against premeasured characteristics of known objects in order to classify the object. The weight of the object can be measured with a scale, and the density of the object calculated, with the weight and density being used by the pattern recognizer to further classify the object. In one embodiment, a plurality of narrowband illumination sources are operated in time-sequential manner, each illuminating with a different wavelength band of light, in order to allow separate color measurements. The object recognition system may be integrated in a single unit along with an optical code reader, and may share all or part of the same exit aperture therewith. The object recognition system may include thermal detection or a particle source and secondary emission detection device, either alone or in conjunction with other object recognition means.

Abstract: A colorimeter provides compensation for changes in the color signature of an object due to lamp aging. A current measuring circuit measures current to the lamp during an initial training of the colorimeter and stores a value I.sub.T indicative of the lamp current at training. When an object is scanned by the colorimeter, lamp current is again sensed and assigned a value I.sub.S. Comparison between a sensed color signature and a stored color signature then occurs. Compensation is accomplished by modifying one of the two signatures by a ratio including I.sub.S and I.sub.T.
