| Summary: | Effect of sampling frequency on variation of absorption cross section for ozone gas measurement is reported. Signal smoothing on ozone gas absorption cross section in the visible spectrum is investigated theoretically and experimentally. Aluminium gas cell of length 0.5 m is used for ozone detection at scan to average between 1 and 100 using Ocean View software. Percentage variations between 0.17% and 11.93% are recorded in comparison with theoretical absorption cross section for ozone detection at wavelength 603 nm. |
