Abstract

The DOAS system is one that combine optics, mechanics, electricity and computer technologies in it. The long optical path DOAS system which we developed is of great sensibility and lower measure limits. It can get the concentration of several kind of trace gases in a given space region simultaneously in the same waveband. This paper provides the method of determining the correspond wavelength in the signal sampling and the method to calculate the delay time.
