Abstract: 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.

Abstract: 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.
