| Zusammenfassung: | The utility model discloses a swash light control system based on TDLAS, this system includes data acquisition module, data processing module, TDLAS drive module. TDLAS drive module is connected with data acquisition module, data acquisition module is connected with data processing module, data processing module is connected with TDLAS drive module, TDLAS drive module is connected with the laser instrument. The first harmonic's that uses through required electric current DC signal of TDLAS drive module lasing ware and analytic solution loading signal comes the driving laser ware for the laser instrument is with the most stable state work, can make loaded signal change after being surveyed the gaseous spectrum that absorbs the laser instrument, and TDLAS drive module carries out the second harmonic demodulation through the signal of holding the detector, thereby reachs the change of signal. TDLAS drive module is all signals for the conversion that digitizes to data acquisition module to the analytical concentr |
