Abstract: A measurement device is described for the quality control of printed products, having a pair of optical channels that differ in their properties and operate simultaneously. Each optical channel comprises an illumination channel for illuminating a measurement location and a reflection channel that picks up the light reflected from the measurement location. The reflected light is directed to an evaluation unit, which is connected to the reflection channel, that analyzes the reflected radiation spectrally. Polarization filters arranged in one of the pairs of channels provides the difference in the optical properties between the two pairs of channels. The measuring device provides an increased number of obtainable measured values for further processing in a way that requires only a modest increase in the metrological outlay compared to other measuring devices of this type.

Abstract: The invention is a colorimeter for dental applications comprising a hand-held probe, similar in size to a dental drill, attached by an electrical cable to a small self-contained display module. The calorimeter provides the capability for measuring the colors of a number points along a line on the surface of an object such as a tooth. A measurement is made while placing the tip of the probe against, or in close proximity to, the surface of the object. The display module to which probe attaches contains a microprocessor and provides a control, display and data interface to the operator. The display module can be adapted for fastening to the wrist of the operator thereby leaving both hands free to manipulate the probe and other tools. The calorimeter is particularly well suited for measuring the color of teeth in a dentist's office in preparation for making dental prostheses which accurately match the color of natural teeth. The colorimeter generates from a single measurement an array of color data points measured along a line on the surface of an object. From those data points, the processor can perform statistical analysis yielding a single color value, generate and display a color profile along a surface, compare measured values with a preloaded table of values, or upload color data to a remote location for laboratory or manufacturing purposes. The colorimeter can also use variations in the color values measured along a line to identify boundaries of areas on a surface. For example, the color profile can be used to identify the gum line on a tooth. The probe comprises multiple light emitting diodes (LEDs) for successively emitting light of different colors toward a surface, a linear photosensor array for receiving light reflected from the surface, and a lens for directing light from the target to the array, all contained within the probe itself. The calorimeter may also comprise a cradle for storing the probe and display module when not in use. The cradle may provide a battery charger, calibration references, and data links for uploading or downloading data from a remote location.

Abstract: A color measurement instrument wherein the communication protocol used by the instrument is determined by the cable attached to the instrument. The instrument includes a handheld unit having a control system capable of communicating in at least two different protocols through a common connector. This control system connector includes a set of pin-outs corresponding to each of the available protocols. The instrument also includes a cable having a connector mated with the control system connector. The pin-out of the cable connector corresponds to only one of the sets of pin-outs of the control system connector, so that the cable provides a communication pathway corresponding to only one of the available protocols.

Abstract: An imaging system for obtaining an image of a field-of-view where high levels of light from an extraneous source may be present at one area and low levels of light present at other areas in the field-of-view. The imaging system has a lens to focus an image of the field-of-view onto a surface of a photodetector and an optical limiter is located between the lens and the photodetector. The optical limiter limits transmission of the high levels of light at areas onto which those are focussed by the lens but remains transmissive to the low levels of light at other areas. The imaging system is particularly intended for use in laser warning receivers where sunlight may be focussed on the optical limiter and blocked at the particularly area on which it is focussed, the optical limiter remaining transmissive to laser beams, even if intense, at locations other than where the sunlight is focussed allowing laser beams to be detected by the photodetector.

Abstract: A portable color measuring device is provided that includes a hand-holdable housing. The color measuring device is configured to receive an independently operable processing device that is mounted to the housing. The independently operable processing device is a portable general purpose computer that executes software applications to control the operation of the color measuring device and process color data. The color measuring device measures the color properties of a sample by illuminating the sample with a light source. The measured properties are processed and/or analyzed by the independently operable processing device and results are displayed to a user. Software applications reside on the independently operable processing device allowing software upgrades or modifications to be easily performed. New applications can be downloaded to the processing device or the processing device can be interchanged with a different processing device.

Abstract: The specification discloses a handheld color measurement instrument including a housing adapted to be held by a human hand. A plurality of support rollers support the housing for movement in a linear direction. A color measurement engine is contained within the housing and includes an aperture opening through the bottom of the housing. The housing includes a pair or pairs of elements defining a line parallel to the linear direction and aligned with the aperture to facilitate alignment of the instrument for scanning. The color measurement engine within the housing includes photodetectors on only one side of the aperture, enabling the aperture to be positioned adjacent the nose of the housing. The support rollers are proximate the perimeter of the housing, and an encoder wheel is inward of the support rollers and proximate the aperture. The instrument is capable of reading barcodes, for example for configuring the instrument, and of reading color samples.

Abstract: A color measurement instrument with improved sample targeting or positioning. The system includes an integrating sphere, a beam splitter, a video camera, and a spectrograph. The beam splitter is aligned with the viewing port of the spectrophotometer to deliver the light reflected from the sample to both the video camera and the spectrograph. The video camera provides an image of the position of the sample with respect to the viewing port of the sphere, enabling the visual observation and evaluation of the sample position prior to use of the spectrophotometer.
