Interfacing the Analogic 6000A Waveform Analyzer to the XM21 Chemical Remote Sensor
Abstract
The XM21 is a Fourier Transform Infrared (FTIR) Spectrometer that is based on a Michelson interferometer. The XM21 operates in the 8 to 12 micron region of the radiation spectrum. This spectral region is one of two atmospheric windows that permits the use of FTIRs for chemical standoff vapor detection. Detection of a compound in this spectral region with the FTIR requires that the compound of interest possess a dipole moment. Many compounds of interest meet this criteria. Identifying pollutants present in the atmosphere is often possible. The purpose of this report is to describe a procedure for obtaining vapor phase data from the XM21 Remote Sensor with an Analogic 6000A Waveform Analyzer (WFA) (Analogic Corporation, Peabody, MA). This approach permits acquisition of data in a variety of formats that depends upon the sensor application. The Michelson interferometer consists of an optical beam splitter, fixed mirror, and moving mirror.
