摘要： A first optical system (10) according to the present disclosure includes a first lens (111) that guides light (LO) to a diffraction grating (3), a second lens (112) that collimates first diffracted light (L1) that was focused at a first focal point (f1), a pair of first mirrors (12, 13), a third lens (113) that focuses the first diffracted light (L1) at a second focal point (f2), and a fourth lens (114) that guides the first diffracted light (L1) that was focused by the third lens (113) to the diffraction grating (3). The first lens (111) and the fourth lens (114) have a substantially identical first focal length. The second lens (112) and the third lens (113) have a substantially identical second focal length. A first distance along an optical path from the first focal point (f1) to the second focal point (f2) is determined by a first predetermined condition.

摘要： A hyperspectral sensing device may include an optical collector configured to collect light and to transfer the collected light to a sensor having spectral resolution sufficient for sensing hyperspectral data. In some examples, the sensor comprises a compact spectrometer. The device further comprises a power supply, an electronics module, and an input/output hub enabling the device to transmit acquired data (e.g., to a remote server). In some examples, a plurality of hyperspectral sensing devices are deployed as a network to acquire data over a relatively large area.

摘要： The present invention discloses a multichannel broadband high-resolution spectrograph, comprising a plurality of light source incident slits, a multichannel integrated grating, a multichannel shared two-dimensional focus imaging mirror and a two-dimensional area array detector which are sequentially disposed along a light source incident or reflection line, wherein the multichannel integrated grating consists of a plurality of sub-gratings, incident light enters the corresponding integrated gratings along the light source incident slits and then is focused by the shared two-dimensional focus imaging mirror after diffraction of the integrated grating, and diffraction light in a full-spectrum region is incident onto a focal plane of the two-dimensional area array detector for detection. No any mechanical displacement part is disposed, multichannel, full-spectrum and high-speed detection and analysis is achieved, and the present disclosure has high spectrum resolution and working reliability.

摘要： An optical emission spectrometer has an excitation device for a sample to be examined, a dispersive element for spectrally decomposing light emitted by an excited sample, a multiplicity of photodiodes, which are arranged such that different spectral components of the emitted, decomposed light are detectable with different photodiodes, and a multiplicity of electronic readout systems for the photodiodes. A respective electronic readout system has a charge storage assembly comprising a plurality of individual charge storage devices, wherein the charge storage devices are interconnectable in cascading fashion, with the result that charges flowing in from an associated photodiode successively fill the charge storage devices. The respective electronic readout system can be used to read the charges of the individual charge storage devices of the charge storage assembly and/or the charges of subsets of the charge storage devices of the charge storage assembly.

摘要： A spectrophotometric device is disclosed having a plurality of spectral measurement bands including a single telescope and a single spectrophotometer. The plurality of spectral bands is obtained by placing pupillary separating prisms at an entrance pupil of the telescope, and by using spectral band selection filters. Such a device has a lower weight, smaller dimensions, and a lower price. In particular, it may be integrated into a satellite, in particular for a mission to characterize flows of carbon compounds that are produced on the Earth's surface.
