Abstract: A color analyzer is capable of determining the color property of a test object, and includes a light collector having a first end formed with a test opening and adapted to be placed in juxtaposition with the test object, a second end, and a light channel extending from the test opening to the second end. A lighting unit is mounted on the light collector, and is operable in order to generate light outputs of different wavelengths. A color filter device is movably disposed in the light collector, and includes a transparent filter and three color filters. A filter-shifting unit is associated with the color filter device, and is operable so as to move the color filter device in the light collector in order to align the filters within the light channel. A photoelectric sensor produces an electric output signal corresponding to the light leaving the color filter device. A signal-processing unit is connected to the photoelectric sensor to process the output signal of the photoelectric sensor in order to determine the color property of the test object.

Abstract: A color classification system and method for classifying, judging and/or identifying objects by color. An optical system utilizes light from an object to form an image on an imaging device. A plurality of optical band-pass filters each having a different pass band are provided between the object and the imaging device. The optical band-pass filters include a plurality of measurement filters for use in measuring a color of the object and a test filter for use in judging which one of the measurement filters should be applied to the object. A changeover section changes between the optical band-pass filters. A computing circuit performs at least one of a color classification and a color judgment based on a spectral characteristic of the imaged object through a statistical approach, and a control section causes the changeover section to select an effective one of the measurement filters based on a judgment by the computing circuit of a result sensed by the test filter. The plurality of optical band-pass filters are arranged in a plurality of filter sets each of which has at least one filter, and the changeover section includes a filter changeover mechanism for changing between the optical band-pass filters in one of the filter sets, and a filter-set changeover mechanism for changing between the plurality of filter sets.

Abstract: A scanning monochromator includes a plurality of diffraction gratings mounted on a rotatable turret, so that each grating may be moved and precisely indexed into operative position. Each grating so positioned is angularly rotated about its axis by the same scanning arm, driven by a cam having two similar (but different) contours for producing one of two similar scanning functions for the various gratings. Preferably more interchangeable order-separating filters than gratings are included to insure complete and efficient filtering (e.g., 14 filters for 7 gratings). Both the stepping of the grating turret and of the filters (e.g., on a filter wheel) are controlled by (digital) signals, derived from the actual wavenumber being separated, as precisely read by (coarse and fine) digital encoder discs on the wavenumber scanning driving shafts (before and after a large-ratio reduction system). The digital control signals and a signal indicating the operative grating provide a readout of the wavenumber, directly usable by data processing apparatus. The closed loop digital nature of the control signals are free of any non-systematic errors, and allow the instrument to be ''''indexed'''' to any desired wavenumber (and then ''''instructed'''' to scan to any other wavenumber automatically).

Abstract: A spectrometer and method of spectroscopic analysis for providing spectral data concerning a scene by collecting and collimating radiation from the scene to provide a radiation beam dispersing the radiation of the beam into a spectrum, forming a focused image of the spectrum, scanning the spectrum image in rapid succession by multiple narrow radiation receiving areas, and generating an electrical output representing the radiant flux incident on each area during its relative scanning movement along the image. The spectrometer may be equipped with means for mounting radiation filters over selected radiation receiving areas to provide information concerning selected characteristics, such as relative polarization, of the radiation from the spectrum image and for mounting narrow band-pass calibration filters over alternate radiation receiving area to permit calibration of the spectral data obtained from the scene.

Abstract: A fluorescence detection system is provided and adapted to provide a selectable excitation beam to an optical transmission path for irradiation of a device under test, including a driving module, a lighting module, a first optical module and a second optical module. The driving module includes a first shaft and a second shaft parallel thereto. The lighting module is fixed to the first shaft. The first optical module and the second optical module are fixed to the second shaft. A driving operation enables the driving module to rotate the lighting module, the first optical module and the second optical module simultaneously, determining quickly a combination of one light source, one filter and one spectroscopic module on the optical transmission path, with the combination corresponding in position to the device under test, so as to reduce the volume and cost the fluorescence detection system.
