Abstract

The invention discloses a real-time data processing system and method for a time-modulated spectrometer. The system includes: a data transceiver module for receiving three scenarios of the first calibration source, the second calibration source and the target from the instrument data acquisition system Interference data; it is also used to receive the processed data from the data processing module, and output the processed data according to actual needs; the control module is responsible for controlling the data receiving and sending module to complete the receiving, storing and sending of data; responsible for controlling the work of the data processing module , to provide timing and logic control commands for the data processing module; the data processing module is used to complete the real-time data processing of the three scene interference data received by the data sending and receiving module. This patent can be used in airborne, balloon-borne or space-borne time-modulated spectrometers, and on-line detection applications where data volume is limited or real-time target spectra are required. It has the advantages of convenient hardware implementation, flexible application, good real-time performance, high precision and high reliability.

Description

technical field [0001] The invention relates to a real-time data processing system and method for a time-modulated spectrometer. Background technique [0002] Temporal interference spectroscopy has the advantages of high spectral resolution, high luminous flux, multi-channel, and wide spectral coverage. It is a very important high-resolution spectral analysis technology, especially for broadband infrared spectral detection. At present, it has been widely used in space remote sensing, atmospheric detection, material analysis, security and chemical defense, measurement, laboratory, environment, medical treatment, military analysis, criminal investigation and other fields. [0003] Different from the traditional prism, grating spectrometer, and filter spectrometer, the time modulation spectrometer splits the target incident light based on the principle of time modulation, so the amount of data it acquires is particularly large, and the amount of data is positively correlated wi...

Problems solved by technology

[0007] 1) At present, the direct download or storage method generally adopted has a large amount of downloaded data and high storage pressure, which is difficult to meet the application requirements;

[0008] 2) Using a compression algorithm for compression processing has problems such as poor compression capability, single means, and complex algorithms;

[0009] 3) The extraction filtering method needs to be further improved in compression ability, but it has a great impact on the signal-to-noise ratio of the restored spectrum;

[0010] 4) At present, spectral restoration is generally implemented based on computer software, which has problems such as slow speed and difficulty in meeting real-time requirements in some applications
