    Abstract: A colorimeter for reading color bars of printed sheets or the like includes a longitudinally extending base including a paper stop along which a sheet to be tested for color may be positioned. An autonomously operating colorimeter head is moved along the base in a direction parallel to the edge of the sheet by means of an electric motor mounted on the base and driving an helical thread lead screw engaging an X-axis carriage supporting the head. The head is moved by operation of the lead screw in a direction parallel to the edge of the sheet, referred to as the direction of the X-axis. The head includes an electric motor and a Y-axis transport supporting an optics unit. The optics unit is moved within the head in a direction parallel to a Y-axis, extending perpendicularly to the X-axis. The optics unit is preferably a spectrophotometer including a rotating wheel provided with a plurality of individual filters, spaced apart along the periphery of the wheel. The individual filters each pass light of a predefined wavelength onto a single photodetector and the signal derived from the photodetector is integrated over a period of time to provide an output signal representative of the intensity of a particular wavelength.

    Abstract: A color measuring system includes a portable spectrophotometer connectable to a general-purpose computer. The portable unit includes a microprocessor with a read-only program memory storing machine executable instructions to implement data processing for color measurement purposes and input/output functions including key reading and data transfer functions and display functions. A random-access data memory is used to temporarily store process data for later transfer to the general-purpose computer. An editor program and a compiler program in the general-purpose computer may be used to generate a program for the microprocessor using high-level, generalized commands. After such a program has been written and compiled in the general-purpose computer, it is transferred to a command buffer area in the random-access data memory of the microprocessor. The microprocessor, in its program memory, includes a command interpreter including a predefined sequence of machine executable instructions for each generalized command. When executed, the command interpreter reads a generalized command from the data memory and, if necessary, updates relevant data pointers and executes the predefined sequence of machine executable functions in the program memory corresponding to the generalized command being processed. A user, using the general-purpose computer, may specify any desired sequence of measurement operations by specifying functions to be performed by the microprocessor, including the display of prompts to the operator of the portable spectrophotometer to instruct the operator to perform various specified operations.

The light source may in the preferred embodiment be the sun or the sample itself and a reference optical path is used for reference which is the same optical path as the optical path from the light from the sample. The tristimulus values X, Y, Z and the chromaticity coordinates x, y of the sample with respect to the CIE standards for luminance and chromaticity values are produced for accurate color measurement.

    Abstract: A novel apparatus for the measurement of color of a sample which comprises an illumination means to illuminate the sample, an electro-optical sensing head to receive the light from the illuminated sample and to output electronic signals and an electronic processing unit adapted to process the signals. The system uses, in the preferred embodiment, a moving spatial filter to modulate a spectrum and a masking means to selectively mask the light from the modulated spectrum. A reference optical path and reference light signals are produced for subsequent processing with the light from the sample, corrected for any errors produced and processed in an analogue electronic unit to produce the tristimulus values X, Y, Z and the chromaticity coordinates x, y of the sample with respect to CIE standards for luminance and chromaticity values.
