Paper Abstract

A fast-response infrared spectrometer was constructed by using an AgI/Ag-coated hollow fibre and a PtSi CCD sensor array. The infrared transmitting hollow fibre was employed as a gas-flow cell to reduce both sample volume and sampling time. The infrared beam that passed the hollow fibre was diffracted by a grating, and was detected by the sensor array with a 1/60-s frame time. Spectra of flowing CH4 and CO2 gases were measured successfully in the 3-4-μm wavelength range.
