Abstract: A cavity-enhanced absorption spectroscopy instrument has an optical cavity with two or more cavity mirrors, one mirror of which having a hole or other aperture for injecting a light beam, and the same or another mirror of which being partially transmissive to allow exit of light to a detector. A spherical-spherical configuration with at least one astigmatic mirror or a spherical-cylindrical configuration where the spherical mirror could also be astigmatic prevents a reentrant condition wherein the injected beam would prematurely exit the cavity through the aperture. This combination substantially increases the number of passes of the injected beam through a sample volume for sensitive detection of chemical species even in less than ideal conditions including low power laser or LED sources, poor mirror reflectivity or detector noise at the wavelengths of interest, or cavity alignment issues such as vibration or temperature and pressure changes.

Abstract: A spectrometer (100) and an optical input portion (32) thereof are disclosed. The optical input portion (32) comprises an assembly structure (322), and the assembly structure (322) is formed at a hole wall (321) of a through hole (3211) of the optical input portion (32). A light (L1) is incident into a dispersing element (2) of the spectrometer (100) along an optical path (13) after passing through the through hole (3211), and is dispersed by the dispersing element (2). The assembly structure (322) is used to be detachably assembled with an optical element (200). When the optical element (200) is assembled with the assembly structure (322), an optical axis of the optical element (200) is linked to the optical path (13). As a result, the light (L1) passing through the optical element (200) is incident to the dispersing element (2) along the optical axis and the optical path (13).

Abstract: This spectral-image-obtaining device includes: a line-spectral-image acquiring unit that acquires a plurality of line spectral images; a frame-image acquiring unit that has an image-capturing range that encompasses that over which image capturing is performed by the line-spectral-image acquiring unit and that acquires a two-dimensional frame image that contains fewer color signals than the line spectral images; a comparison-image estimating unit that estimates comparison images for all lines based on the line spectral images acquired by the line-spectral-image acquiring unit and a wavelength characteristic of the frame-image acquiring unit; a line-spectral-image positional-deviation detecting unit that detects amounts of positional deviation between the comparison images estimated by the comparison-image estimating unit and corresponding positions within the frame image; and a positional-deviation correcting unit that fits the line spectral images to corresponding positions within the frame image based on the amounts of positional deviation detected by the line-spectral-image positional-deviation detecting unit.

Abstract: A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.

Abstract: A method for two-dimensional, spatially resolved measurement of tristimulus values of light emitted from a plurality of positions on a sample. In various embodiments, an improved method and system is provided for spatially resolved chromaticity and luminance measurement in a standardized color space for display testing. The method may include directing a first portion of the light to an RGB camera which produces a two-dimensional map of RGB color values; transforming the RGB color values into first tristimulus values to produce a map of tristimulus values; directing a second portion of the light to a colorimeter which produces second tristimulus values; deriving a tristimulus correction by comparing the second tristimulus values with at least a subset of the first tristimulus values; and applying the tristimulus correction to the first tristimulus values to produce a corrected map of tristimulus values. In many embodiments, the imaging colorimeter system is capable of two-dimensional, spatially resolved measurement of tristimulus values of light emitted from a plurality of positions on a sample.

Abstract: A compact wavelength dispersing device and a wavelength selective optical switch based on the wavelength dispersing device is described. The wavelength dispersing device has a folding mirror that folds the optical path at least three times. A focal length of a focusing coupler of the device is reduced and the NA is increased, while the increased optical aberrations are mitigated by using an optional coma-compensating wedge. A double-pass arrangement for a transmission diffraction grating allows further focal length and overall size reduction due to increased angular dispersion.

Abstract: The invention relates to controllable Fabry-Perot interferometers which are produced with micromechanical (MEMS) technology. Micromechanical interferometers of the prior art have a disadvantage of significantly attenuating infrared radiation. In the inventive solution there is a gap in at least one mirror, serving as a layer of the mirror. The other layers of the mirrors can be made of polycrystalline silicon, which has a negligible attenuation at the infrared range. It is also preferable to provide a hole or a recess in a substrate at the optical area of the interferometer.
