Device and method for collecting space two-dimensional spectrum data

Abstract

The invention discloses a device and a method for collecting space two-dimensional spectrum data, which mainly solve the defect that the prior unit detector type Fourier infrared spectrum radiometer and the infrared imaging spectrum radiometer are inconvenient to use or have low spectrum resolution when collecting two-dimensional space spectrum distribution data. The prior unit detector type Fourier infra-red spectrum radiometer is additionally provided with a two-dimensional scanning mechanism with automatic adjustment, and the collection of two-dimensional spectrum data is completed by controlling the rotation of a plane reflector arranged on a two-axis electric-control automatic revolving table in the two-dimensional scanning mechanism. A synchronous controller is connected with a spectrum radiometer and the two-dimensional scanning mechanism to synchronously control the scanning of the two-dimension scanning mechanism and the spectrum data collection, and finally a data cube comprising one-dimensional spectrum information of high spectrum resolution and plentiful two-dimensional space information is formed. The invention enhances the collection efficiency and the space collection precision of spectrum radiation data and can be used for infrared target spectrum imaging and target spectrum analysis.

Description

technical field [0001] The invention relates to the application field of spectroradiometers, in particular to a collection device and method for spatial two-dimensional spectral data of a Fourier infrared spectroradiometer, which can be used for infrared target spectral imaging and target spectral analysis. Background technique [0002] An infrared spectroradiometer is an instrument that measures the emission spectrum of an object in the infrared band. By obtaining the infrared spectral radiation of the object, the infrared spectral analysis technology can be applied to the characteristic analysis of the object, such as determining the peak intensity, position and shape of the infrared emission spectrum of the object, analyzing the infrared spectral absorption characteristics of the object, especially the gas, etc., and then completing Agriculture, environment, geology, petroleum, security, military and many other military and civilian application requirements, such as the g...

Problems solved by technology

However, there are two problems with this method: one is that the high-performance infrared spectroradiometer is cooled by liquid nitrogen, so the adjustment of the pitch angle is limited. If the pitch angle is too large, the liquid nitrogen will leak, which poses a safety hazard. ; Second, this kind of manual adjustment cannot guarantee that each adjustment is strictly consistent, which will cause problems for subsequent data processing

[0008] It can be seen from the above analysis that since the infrared spectral data cube containing spectral distribution and spatial distribution contains a large amount of information, it has very important significance for practical applications in many fields, while the existing unit detector type Fourier infrared spectroradiometer and Infrared imaging spectroradiometers have defects such as inconvenient use or low spectral resolution when collecting two-dimensional spatial spectral distribution data
