Problems solved by technology

Therefore, limited by the physical resolution limit of the gradient filter itself, the infrared spectroradiometer based on the spectrum of the gradient filter can no longer meet the application requirements well in some applications, and there is a bottleneck problem of spectral resolution capability.

Abstract

The present invention relates to a broadband infrared spectroradiometer spectral resolution enhancement method based on a gradual filter and a broadband infrared spectroradiometer. The method comprises: performing spectrum sampling of incident infrared signals, obtaining each wavelength channel of a gradual filter, performing secondary sampling of the overlapping region of any two adjacent wavelength channels in each wavelength channel, constructing a middle wavelength channel according to a spectrum peak position obtained through the secondary sampling, and realizing the spectral resolution enhancement of the broadband infrared spectroradiometer. The spectral resolution enhancement method does not need updating of hardware, only needs to add finite spectrum sampling and performs proper data processing to realize the enhancement of the spectral resolution of the broadband infrared spectroradiometer based on the gradual filter, and is simple and efficient.

Description

technical field [0001] The invention belongs to the field of broadband infrared spectroradiometers, and in particular relates to a method for enhancing spectral resolution of a broadband infrared spectroradiometer and an infrared spectroradiometer. Background technique [0002] Broad-band infrared spectroradiometer is a kind of measurement system that integrates the functions of spectrometer and radiometer. Many scientific research, production and other occasions. [0003] The filter spectroscopic system is a commonly used spectroscopic system for infrared spectroradiometers. Gradient filter is a new type of filter that is widely used at present. Compared with traditional filters, its wavelength coverage and spectral resolution have been significantly improved. Gradient filter is a new type of ultra-narrow-band filter whose wavelength increases or decreases uniformly along a certain direction. The gradient filter is driven by a high-precision motor, so that the incident l...
