Abstract: A spectrophotometer for measuring a two-dimensional area or a spot area in a rather broad surface of a sample, where the spectrophotometer is provided with a camera for taking the picture of the sample surface. The picture is shown on a display screen, and the operator can move a window superimposed on the sample picture in the display screen by using a mouse or the like to a desired place on the sample surface. The sample stage on which the sample is mounted moves according to the movement of the mouse, whereby a spectrophotometric measurement of the desired place (two-dimensional area or the spot area) on the sample is facilitated.

Abstract: A method and apparatus for classifying articles according to their color, wherein a first pair of wavelengths is selected on a plurality of light reflection curves in terms of a reflected light wavelength spectrum. An article to be inspected is illuminated with light comprising the first pair of wavelengths and light reflected therefrom is measured to detect light reflection values corresponding to this first pair or wavelengths. A primary signal is produced, which represents a resulting difference between the detected light reflection values, this signal being indicative of the color of the inspected article. At least one secondary wavelength is selected on the reflected light wavelength spectrum, and the inspected article is illuminated with light comprising this secondary wavelength and light reflected therefrom is measured to produce a secondary signal which is further indicative of the color of the inspected article. A computer provides a classification frame comprising a first pattern consisting of a first and second crossing set of lines respectively defined by mathematical analysis, this classification frame defining a plurality of color classes. The computer classifies the inspected article in one of the plurality of color classes defined by the frame whenever the primary and secondary signals comply with a specific condition. The computer rejects the inspected article whenever the primary and secondary signals do not comply with this specific condition.

Abstract: Method and apparatus for sensing the color of articles wherein a first pair of wavelengths is selected on a plurality of light reflection curves in terms of reflected light wavelength spectrum, these curves being associated with a plurality of articles constituting a sample representative of the color range to be sensed. The first pair of wavelengths delimits a first range of wavelengths corresponding to light reflection values in these curves, the light reflection values in each of the curves being in a substantially linear relationship over said first range of wavelengths. Each article to be inspected is illuminated with light comprising the first pair of wavelengths, and the light reflected therefrom is measured to detect light reflection values corresponding to the first pair of wavelengths. A primary signal is produced which represents a resulting difference between said detected light reflection values, this signal being indicative of the color of the inspected article.

Abstract: A manual device for the detection of photometric data which includes a measuring head to illuminate a measuring surface and to detect the light reflected. The measuring light captured by the measuring head is spectrally decomposed by a monochromator containing a diffraction grating. The intensity of the light exiting through an outlet diaphragm is detected by a photodetector. The spectral position of the measuring light is set by a drive motor rotating a grating shaft connected with the holder of the diffraction grating. From the spectra detected, densitometric and colorimetric data are calculated by a computer, which together with the spectra determined, may be displayed on a display field.

Abstract: An improved color sensor is provided having two sources of illumination, one source being modulated on and off while the other source remains on. Data taken while the modulated source is on is compared with data taken while the modulated source is off to compute the effective fluorescence of the sample. A corrected color spectrum can then be determined for a defined source.

Abstract: A scene is scanned with several different frequency light beams, emitted for example, from a mixed gas laser. The scattered light returned from the surfaces of the objects in the scene is detected. Comparing the phase of the returned light with the emitted light provides range information. The amplitudes of the signals of the various different frequency light beams are logically combined to provide the color at each point of the various surfaces within the scene. From the combined range and color information machine analysis of the scene can be made so that the objects in a cluttered scene can be recognized by the machine.

Abstract: The colors of individual picture elements in a fabric pattern design are encoded by comparing the level of transmittance or reflectance of the picture element at preselected wavelengths with stored values representing a reference color to generate a multibit code indicative of the color of the picture element. A comparator used for this purpose incorporates an error either proportional to the wavelength or of constant value so that the output of the comparator will indicate identity with the stored value if the input value for the picture element is within a certain range of the stored value.
