Abstract: A portable colorimeter for characterizing the optical properties of a colored surface and in particular a colored surface containing metallic or pearlescent particles, which employs three multiangular spectrophotometric measurements to derive color constants for the surface. The colorimeter is a compact integrated unit housing irradiation, detection, control, analysis and display means and employs three illumination angles, preferably -30°, O°, and 65°, and one detection angle, preferably 45°, all measured from the sample normal. The method includes determining the tristimulus values of the color of the sample surface from low resolution spectral reflectance data preferably using twelve detector elements.

Abstract: The invention makes it possible to determine the colour to be given particularly to a dental prosthesis from the measurement of the colour of adjacent teeth in the mouth of the patient. An optical fiber instrument (44) senses the light reflected by a tooth (50) and transmits the light to the input of a spectrocolorimeter (12, 14) associated with a microprocessor (10) in order to determine the spectral reflectance diffused by the tooth and to calculate the trichromatic components of its apparent colours for various types of lighting. The invention applies particularly to the determination of colours of dental prostheses.

Abstract: In an optical instrument for spectroscopically measuring color and gloss of a sample surface, a fiber optic probe is provided wherein light is transmitted from a light source to the probe through a fiber optic bundle. The fiber optic bundle is arranged to illuminate a surface positioned over an aperture in the probe. Light diffusely reflected from the sample surface is transmitted by a second fiber optic bundle to a spectrophotometer. A small fiber bundle is arranged in the probe to irradiate the surface of the sample at an angle of 60 degrees and a second small fiber bundle is arranged to receive light from the first mentioned small fiber bundle after being specularly reflected from the surface. The second fiber optic bundle transmits the received light to a photodetector in the spectrophotometer to provide an indication of the gloss of the sample surface.

Abstract: An imaging system includes a light source configured to illuminate a target and a camera configured to image light responsively emitted from the target and reflected from a spatial light modulator (SLM). The imaging system is configured to generate high-resolution, hyperspectral images of the target. The SLM includes a refractive layer that is chromatically dispersive and that has a refractive index that is controllable. The refractive index of the refractive layer can be controlled to vary according to a gradient such that light reflected from the SLM is chromatically dispersed and spectrographs information about the target can be captured using the camera. Such a system could be operated confocally, e.g., by incorporating a micromirror device configured to control a spatial pattern of illumination of the target and to modulate the transmission of light from the target to the camera via the SLM according to a corresponding spatial pattern.

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.
