Compressive Sensing Echelle Spectrometer
Frontiers in Optics 2009/Laser Science XXV/Fall 2009 OSA Optics & Photonics Technical Digest, 2009A compressive sensing echelle spectrometer has been built. By employing compression, we reconstructed the two dimensional echelle spectrums using the single photodetector with far fewer measurements when compared to raster scanning.

Single-pixel echelle spectrometer based on compressive sensing
Optik, 2021Abstract In this paper, a single pixel echelle spectrometer system based on compressed sensing theory is proposed. The Digital Micromirror Devices (DMD) is used as the Coding board, and the photomultiplier of high sensitivity point detector is used as the signal receiver.

Compact echelle spectrometer employing a cross-grating
Applied Optics, 2018The concept and the implementation of a compact and simplified echelle spectrometer are presented, and the working principle is demonstrated by first experimental measurements. The crucial element of the setup is a cross-grating, combining an echelle grating utilizing several higher diffraction orders (5th up to 11th) and a superposed perpendicular ...

Echelle spectrometers and charge-coupled devices
Spectrochimica Acta Part B: Atomic Spectroscopy, 1997Abstract State-of-the-art spectrometers are equipped more and more with solid-state array detectors for the recording of spectra. The basis of this development is the tremendous improvement in the performance of detectors. The photometric parameters of individual pixels of detectors (quantum efficiency, dark current, read-out noise) are comparable to

An echelle diffraction grating for imaging spectrometer
SPIE Proceedings, 2016We demonstrate an echelle diffraction grating (EDG) of 17 input waveguides and 33 output waveguides. For each input waveguide, only 17 of 33 output waveguides are used, receiving light ranging from 1520 nm to 1600 nm wavelength. The channel spacing of the EDG is 5 nm, with loss of -6dB and crosstalk of -17dB for center input waveguide and -15dB for ...

Echelle-emission spectrometer with divided spectral coverage
Optics and Precision Engineering, 2014Limited by the development of detectors, the Inductively Coupled Plasma Atomic Emission Spectrometry(ICP-AES) based on an echelle spectrograph is difficult to complete the multiple element measurement at a wider spectral coverage. This paper focuses on the improvement of an existing echelle spectrograph. It designs a new wider band echelle spectrograph
