Based Stm32 Embedded Spectrum Reconstruction Processing Technology

Due to the advantages of high throughput, high spectral resolution and high imaging stability, interference imaging spectroscopy has become the advanced subject in the realm of remote sensing technology and its application. It can obtain abundant spatial and spectral information of the detected object, with its wide use in both military and civilian areas. The reconstruction of interferogram is an important problem of the imaging spectroscopy, and the main work of this paper is to establish a small embedded system for reconstruction process. First, the software and hardware environment to develop STM32 processor with the core of Cortex-M3 is introduced. Second, the reconstruction algorithm and its transplant to embedded system is studied. Then, the whole system is divided to three functional module:data transmission module, file access module, display and control module. After programming and debugging of each, their combination becomes the final embedded system for spectral reconstruction process. Finally, recovered spectral data from the embedded system is compared to that from MATLAB program, and the results show that the spectral resolution has achieved the specified requirements.
