Abstract

The invention discloses a spectrum reconstruction method. The method comprises the following steps of: initializing an optical filter, namely acquiring a transmission spectrum curve of each optical filter channel on the optical filter; acquiring a spectrum, namely acquiring initial spectrum information after light is transmitted into the optical filter; and performing spectrum reconstruction, namely reconstructing the initial spectrum information to acquire the reconstructed spectrum information by using the transmission spectrum curves through a non-negative matrix factorization (NMF) method. The spectrum information of probing light is acquired by reconstructing the spectrum information acquired by an image sensor. The invention also discloses a spectrometer device.

Description

technical field [0001] The invention belongs to the technical field of spectrum analysis, and in particular relates to a spectrum reconstruction method and a spectrometer device thereof. Background technique [0002] The application of spectroscopic technology covers almost all scientific fields, including medicine, chemistry, geology, physics and astronomy, etc. From the bottom of the ocean to the distant universe, spectrometers collect material characteristic information of the surrounding world for people. Since the spectrometer can obtain a large amount of information related to the material structure, it has a wide range of applications, such as concentration analysis, desulfurization and sulfur recovery analysis, tail gas analysis, flue gas analysis, pollution source analysis, colorimetric analysis and turbidity analysis, etc., so it is widely used Environmental monitoring, forensic identification, biomedicine, science and technology agriculture, transportation, resour...
