    Abstract: Method for measuring the colour of a patient's tooth, e.g. for preparing a dental prosthesis, by which method a measuring probe (1) is placed adjacent the tooth, light being emitting from the probe (1) which after reflection from the surface of the tooth is received by the same probe (1). The measuring probe (1) comprises two light conductor members (2, 3), one for transmitting light and one for receiving light, the first light conductor member (2) being formed of a bundle of light conductors concentrically arranged in relation to the second light conductor member (3). A spectroscopic member (7) communicating with a processor means (8) determines the shade of the tooth in relation to a given colour guide.

    Abstract: An object recognition system and method capable of identifying products (29) such as produce in a supermarket. A preferred 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 for separating the color components of the light reflected (32) from the unknown object (29) and directing the color components onto an optical detector (34). The color separator may incorporate a diffraction grating (72) or a holographic element (82). Alternatively it may incorporate a plurality of narrowband illumination sources (92-94) operating in a time sequential manner, each illuminating with a different wavelength band of light.

    Abstract: Disclosed is an apparatus for measuring on-line the color and color-related properties of a moving sheet. Contrast ratio reflectance measurements are made for providing opacity corrections substantially in real time for a full color spectrum. An optical color sensor in accordance with the invention includes a pair of synchrhonized spectrometers, the first spectrometer being aligned to view a region of the sheet backed with a highly reflective ("white") material and the second spectrometer being aligned to view a region of the sheet backed with a higly absorptive ("black") material. The use of two spectrometers permits substantially simultaneous "black" and "white" measurements for a full color spectrum. The optical color sensing system further includes two light sources, a flashlamp and a continuously energized tungsten filament lamp. Light beams from the two sources are combined to form a sheet-illuminating third beam approximating the D65 standard source. The intensity of the flashlamp is electronically controlled to maintain the balance of UV to visible light that characterizes the standard source. The color sensor further includes a sheet backing system including a rotatable standard wheel carrying a white standard tile. Provision is made to permit rotation of the standard wheel and to standardize the sensor off-sheet while maintaining isolation of the white standard tile from the paper mill environment.

    Abstract: The novel spectrum analysis and absorption measurement process with controlled spectral range provides new facilities for spectrum analysis and the measurement of small uneven objects. The use of centring beams makes it possible to measured objects in depth (translucence, opalescence). The use of a CCD sensor instead of the PIN photodiode makes it possible to measure entire 3-dimensional bodies by spectrum analysis. Contact-free measurement means that this measuring process provides new opportunities on the production line and in the automatic production of textiles, paper, paints, foodstuffs, etc.

    Abstract: This specification describes various embodiments that relate to methods for providing a wideband colorimeter that can include more accurate outputs. In one embodiment, a narrowband instrument, such as a spectrometer or spectrograph, can be used for calibration of a wideband colorimeter, so that more accurate outputs can be provided. In one embodiment, an optical test equipment, which consists of both a wideband colorimeter and a narrowband spectrograph, can be used for providing a more accurately calibrated wideband colorimeter. As an example, a spectra-camera, which is a hybrid system consisting of both a wideband colorimeter and a narrowband spectrograph, can be used for simultaneous testing by both the wideband colorimeter and the narrowband spectrograph. By doing simultaneous testing, accurate calibration of the wideband colorimeter can be achieved. This specification further describes a mathematical model to characterize a wideband three channel colorimeter with a narrowband multiple channel spectrometer.
