  • Patent number: 10094841
    Abstract: A control unit outputs measurement status information including the time up to the completion of creation of the calibration curve for each of the desired measurement items to a display unit. The output/display of the calibration curve data measurement status for each of the items enables the operator to be aware of information about a failure to set a standard solution or to request the setting of the standard solution and to recognize how long he or she will need to wait until the creation of the calibration curve begins. The operator can therefore know what can be done while waiting, thereby improving job efficiency.

    Abstract: A device and method of operation for analyzing signal features over multiple optical wavelengths is presented. A plurality of rotating thin film filters is arranged with respect to a collimated beam of light so that each thin film filter transmits light of a particular wavelength to a detector unit responsive to an angle of incidence of light upon the thin film filter when the thin film filter optically interposes the collimated light beam. Each of the plurality of thin film filters is optically interposed periodically and rotated so that the angle of incidence of light from the first input unit upon the thin film filter varies when the thin film filter is optically interposed to scan the light by wavelength within a selected wavelength band into a detector unit for measurement.

The color wheel includes a color filter, which includes three sector-shaped filter segments and a motor for driving the filter segments of the color filter to rotate. The color filter is driven to rotate. Light is emitted toward the color filter of the color wheel, and reflected back by the color filter. Boundary impulses are generated according to changes in intensity of the light reflected back by the color filter. Based on relationships between the boundary impulses, central angles of the filter segments of the color wheel are calculated.
