Abstract: A spectrometry apparatus includes a wavelength variable interference filter emitting light of various predetermined wavelengths; a roll shutter imaging element having pixels accumulating electric charges when exposed to light, and forming one frame by photodetection for each pixel block including pixels with a predetermined time delay for each pixel block, in which the imaging element accumulates electric charges in a photodetection period, and outputs a detection signal in response to the accumulated electric charges in a non-photodetection period; and a spectroscopic controller controlling the wavelength change driving of the emitted light of the wavelength variable interference filter. For the one frame, the spectroscopic controller starts the wavelength change driving at an end timing of the photodetection period of a final pixel block for which the photodetection process is performed at the end.

Abstract: In this color measurement device and method, an entire image and a partial image of a color chart are acquired, respectively, during conveyance of the color chart by a conveyance unit and during re-conveyance of the color chart by the conveyance unit, and an amount of positional deviation of the color chart occurring between the conveyance and the re-conveyance is derived based on the acquired entire and partial images. Then, a color of each of a plurality of patches of the color chart is measured by a color measuring unit, while a measurement position of the color measuring unit is corrected according to the derived positional deviation amount.

Abstract: Provided are a Raman signal measuring method and apparatus which use a difference in a time scale between Raman scattered light and fluorescence. Thus, after exciting light is incident upon a target object, light scattered from the target object may be detected before the target object generates fluorescence in response to the exciting light. As a result, a Raman signal in which background fluorescence is reduced may be obtained.

Abstract: A color sensor array includes a plurality of sensors. Each of the plurality of sensors has a width dimension and a length dimension that is elongated with respect to the width dimension. The length dimensions of the sensors are substantially equal to one another and parallel to an illumination plane. Each of the plurality of sensors includes a face defined by opposing first and second elongated sides and opposing first and second non-elongated sides. The first non-elongated sides of the plurality of sensors are aligned with one another along an axis that is substantially perpendicular to the illumination plane.

Abstract: A fiber grating demodulation system for enhancing spectral resolution by finely adjusting a light splitting grating, includes a laser pump source, a wavelength division multiplexer, a fiber Bragg grating, a diaphragm, a slit, a collimating mirror, a light splitting grating, an imaging focus mirror, and a linear array detector. The laser pump source, the wavelength division multiplexer, the fiber Bragg grating are connected in sequence, the wavelength division multiplexer is connected to the diaphragm. Light emitted from the laser pump source is multiplexed by the wavelength division multiplexer and then enters the fiber Bragg grating, a reflection spectrum of the fiber Bragg grating enters the slit of the fiber grating demodulation system as injected light. After passing through the slit, the injected light is reflected by the collimating mirror, the light splitting grating, and the imaging focus mirror in sequence, and is finally converged to the linear array detector.
