Abstract: A high-resolution optical spectrometer with multiple diffractive optical elements operates under broadband light and enables spectral splitting with 3D diffractive optical elements. Diffractive optical elements are used to provide concentration of light as well as spectral splitting. Depending on the application, the high-resolution optical spectrometer operates with a reflection or transmission diffractive optical element. The number of operating wavelengths, spectral resolution, and operating bandwidth of diffractive optical elements are flexible depending on application.

Abstract: In a Raman microscope, a depth measurement processor performs depth measurement by changing a focal position of laser light along a depth direction of a sample which is an irradiation direction of the laser light with respect to the sample, and meanwhile, acquiring a Raman spectrum of the sample at a plurality of points in the depth direction. The display processor causes Raman spectra obtained at the plurality of points by the depth measurement to be displayed. The display processor can display a surface image of the sample on the stage and a depth image representing a plurality of points in the depth direction and causes, in a case where at least one point of the plurality of points in the depth image is selected, the Raman spectrum corresponding to the at least one point to be displayed.

Abstract: A system and method of dynamically localizing a measurement of parameter characterizing tissue sample with waves produced by spectrometric system at multiple wavelengths and detected at a fixed location of the detector of the system. The parameter is calculated based on impulse response of the sample, reference data representing characteristics of material components of the sample, and path lengths through the sample corresponding to different wavelengths. Dynamic localization is effectuated by considering different portions of a curve representing the determined parameter, and provides for the formation of a spatial map of distribution of the parameter across the sample. Additional measurement of impulse response at multiple detectors facilitates determination of change of the measured parameter across the sample as a function of time.

Abstract: A spectrometer includes a light source that emits a beam into a sample volume comprising an absorbing medium. Thereafter, at least one detector detects at least a portion of the beam emitted by the light source. It is later determined, based on the detected at least a portion of the beam and by a controller, that a position and/or an angle of the beam should be changed. The beam emitted by the light source is then actively steered by an actuation element under control of the controller. In addition, a concentration of the absorbing media can be quantified or otherwise calculated (using the controller or optionally a different processor that can be local or remote). The actuation element(s) can be coupled to one or more of the light source, a detector or detectors, and a reflector or reflectors intermediate the light source and the detector(s).

Abstract: The present disclosure relates to measuring light emission. The teachings thereof may be embodied in emission-measuring devices. For example, a device may include: a sample region; an illumination unit for irradiating the sample region and a sample positioned therein; and a radiation detector. The illumination unit may include: a radiation source; a first dispersive element arranged downstream, decomposing the radiation into spectral components; a first micromirror field arranged downstream; and a second dispersive element arranged downstream of the first micromirror field. The second dispersive element may unify spectral components selected by the first micromirrror field into a common excitation beam.
