Paper Abstract

An all-optical fiber and general halogen lamp based remote measuring system for CH4 is reported. This system, under the control of a microcomputer, has realized fully optical real- time and continuous detection for CH4 by using a 20X5X6 cm3 White cell, in which optical paths up to 2.4 m long as the gas sensor, and a 2.0 km low loss optical fiber as the signal transmission channel are employed. The system utilizes an approach called Time Divided Multiplying Double Wavelength Detection (TDMDWD). It can detect 0- 99.99% of CH4.
