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 spectrographic 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: The present disclosure provides a spectrophotometric colorimeter based on LED light source, wherein the spectrophotometric colorimeter includes an integrating sphere, a coupling light path, and a spectrometer. An inner wall of the integrating sphere is arranged with a composite light source consisting of eight LEDs; a sphere wall of the integrating sphere defines an incident aperture; light emitted from each LED enters an interior of the integrating sphere through the incident aperture and is irradiated onto the inner wall. The coupling light path is configured to couple light at a measurement caliber such that the light can enter an incident split and to eliminate stray light from the inner wall. After emitting out from an observation aperture of the integrating sphere, the light enters the incident split through the coupling light path and is irradiated onto a linear-array sensor after being split by a spectral light path; and different pixels of the linear-array sensor correspond to light radiation strengths at different wavelengths.

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.

Abstract: A spectral colorimetric apparatus includes a housing which includes a side wall. An outer surface of the side wall is an adjustment surface capable of adjusting a position of a linear sensor by moving while attaching the linear sensor to the adjustment surface. The linear sensor is supported by the side wall of the housing while abutting on the adjustment surface and receives a light beam that is dispersed by a concave surface reflection type diffraction element and passes through an opening portion. The adjustment surface is parallel to a tangential line at a part of a Rowland circle of the concave surface reflection type diffraction element, through which a light beam received by the linear sensor passes.
