    Abstract: A color measurement apparatus to which a colorimeter that measures a color of a color measurement target is configured to be attached, includes a support base of the color measurement target, a carriage that supports the colorimeter, a gantry that supports the carriage, a first scanning mechanism that causes the carriage to perform scanning in a first direction on the support base, and a second scanning mechanism that causes the gantry to perform scanning in a second direction, in which the first scanning mechanism includes a first motor that generates a driving force for causing the carriage to perform scanning in the first direction, and a first transmission mechanism portion that transmits the driving force from the first motor to the carriage, and the first motor overlaps the gantry in a third direction.

    Abstract: A method comprises obtaining reference data about a 3D calibration object, the reference data comprising known coordinates for a plurality of points on the object, and obtaining measurement data comprising measurements for the plurality of points on the object, the measurement data having been generated based on scanning of the object by an uncalibrated intraoral scanner. The method comprises comparing the measurement data to the reference data to determine differences therebetween and applying the determined differences between the measurement data and the reference data for the plurality of points to a function to generate a compensation model that compensates for one or more inaccuracies of the intraoral scanner. The compensation model is then stored, wherein the compensation model causes the intraoral scanner to be a calibrated intraoral scanner and is usable to correct measurement errors of the intraoral scanner caused by the one or more inaccuracies of the intraoral scanner.

    Abstract: The present invention relates to improvement in accuracy of an automatic sample detection technique in spectrometry of a microspectroscope.
    A microspectroscope 10 comprises: a light source 12 that emits an excitation light to a sample 20; a condensing lens 16 that emits the excitation light to a predetermined position of the sample 20 and condenses a reflected light or a transmitted light from the sample 20; a spectrometer 24 that detects a condensed light; and an analysis control unit 30 for analyzing a signal from the spectrometer 24; the microspectroscope 10 that uses an observation image of the sample 20 to perform spectrometry, wherein the analysis control unit 30 comprises: an image storage part 32 that converts the observation image to an all-in-focus image to store the all-in-focus image; and a control part 34 that makes the microspectroscope 10 to perform measurement, and the control part 34 uses the all-in-focus image and performs a template matching as a matching action of the image to perform position correction to a position deviation of a sample point that is a target of spectrometry in the sample.

    Abstract: A spectral feature selection apparatus includes a dispersive optical element arranged to interact with a pulsed light beam; three or more refractive optical elements arranged in a path of the pulsed light beam between the dispersive optical element and a pulsed optical source; and one or more actuation systems, each actuation system associated with a refractive optical element and configured to rotate the associated refractive optical element to thereby adjust a spectral feature of the pulsed light beam. At least one of the actuation systems is a rapid actuation system that includes a rapid actuator configured to rotate its associated refractive optical element about a rotation axis. The rapid actuator includes a rotary stepper motor having a rotation shaft that rotates about a shaft axis that is parallel with the rotation axis of the associated refractive optical element.

    Abstract: A spectroscopic assembly may include a spectrometer. The spectrometer may include an illumination source to generate a light to illuminate a sample. The spectrometer may include a sensor to obtain a spectroscopic measurement based on light, reflected by the sample, from the light illuminating the sample. The spectroscopic assembly may include a light pipe to transfer the light reflected from the sample. The light pipe may include a first opening to receive the spectrometer. The light pipe may include a second opening to receive the sample, such that the sample is enclosed by the light pipe and a base surface when the sample is received at the second opening. The light pipe may be associated with aligning the illumination source and the sensor with the sample.

    Abstract: A CubeSat compatible spectrometer including a slit having a first length and first width; a diffraction grating; and a two dimensional focal plane array electromagnetically coupled to the diffraction grating. The 2D focal plane array includes an array of pixels including a plurality of sets of pixels. Diffraction of electromagnetic radiation transmitted through the slit by the diffraction grating forms a plurality of beams, each of the beams comprising a different one of the bands of the wavelengths in the electromagnetic radiation, and each of the beams transmitted onto a different one of the sets of the pixels.
