英文摘要

For low-light or near-infrared absorption spectrum measurements, it is challenging to obtain high resolution spectra due to limitations of exotic array detectors. In this paper, a new spectral measurement method based on compressed sensing (CS) is reported. An experimental spectrometer is constructed and calibrated, and the absorption spectra of two liquid samples are measured. Along with a high resolution, the new method has a better signal-to-noise ratio (SNR) than the conventional scanning spectroscopy technique. The measurement resolution of our experimental system is 0.38 nm. The result of wavelength position calibration is accurate. The peak value of characteristic spectrum of red sample is 730 nm, and that of blue sample are 440 nm and 740 nm. © 2019 Elsevier GmbH
