Abstract:
Cavity enhanced absorption spectroscopy (CEAS) may include a pulsed light emitting diode (LED) configured to emit a light towards a photomultiplier tube (PMT). CEAS may also include a cell, which includes a pair of reflective mirrors located at opposite ends of the cell. The pair of mirrors are configured to bounce the light back and forth a plurality of times increasing the effective path length of the cell. The PMT is configured to detect the emitted light for ozone absorption measurement.
