Vlnočtovo modulačná spektroskopia OH radikálu v laminárnom predmiešanom plameni

Abstract

This bachelor thesis focuses on examining the positions of OH radicals in the laminar flame of a calibration burner. The aim is to refine these positions using a Fabry–Pérot interferometer as a calibration instrument and compare them with positions from spectral databases. The first part introduces the theoretical foundation necessary for understanding the issues addressed in the thesis. The theory includes and explains concepts such as wavelength-modulated spectroscopy, the near-infrared, and laminar flame. It also deals with spectroscopic methods such as tunable laser diode absorption spectroscopy. Descriptions of instruments including the interferometer, laser, and calibration burner are provided. The next section presents the experimental setup along with the schematic diagram and instrument settings. Finally, the results are interpreted, and the experiment is evaluated at the end of the thesis.
