| 英文摘要 | This work described a system of high-speed data acquisition and real-time signal processing based on Tunable Diode Laser Spectroscopy (TDLS). We used wavelength modulation spectroscopy technique to improve the de-noising performance of the system and reduce the acquisition stress of the system. We specially designed a new structure of multi-channel TDLS, through the peripheral multi-channel Analog to Digital Converter (ADC) of the DSP (Digital Signal Processing) to measure multi-channel spectral information, which gives technical support for multi-component gas detection. We also compared the performance of the fixed point DSP with the float point DSP used in the TDLS system. By studying the aspects mentioned above, technical basis is provided for the implementation of standardized multi-channel TDLS system.; CPCI-S(ISTP); 213-216; 123 |
