Function Of Chopper In Spectroscopy at John Whyte blog

Function Of Chopper In Spectroscopy. In the context of spectroscopy. the purpose of the chopper is to provide a means for discriminating against the emission of light from the flame, which will otherwise contribute to the total amount of light that reaches the detector. Instead of directly measuring the optical power with some photodetector , one registers an oscillating power of a chopped beam. As shown in figure \(\pageindex{3}\), when the chopper is closed, the only light reaching the detector is from the flame; A chopper which is placed between the radiation source and the flame is meant to break the continuous light. 3.2.4 chopper a chopper is a device that splits a single beam of radiant light into two directions. a chopper by itself does not eliminate drift, a chopper and a highpass (or bandpass) filter eliminate drift.

(a) Chopper modulated laser excitation and PL signal. (b) MW sequences
