A commercial Fourier transform interferometer system with telescopic optics has been installed in a van and used to make long-path absorption and single-ended emission measurements of gaseous pollutant concentrations at a number of geographical locations. The system covers the IR spectra region from 650 cm(-1) to 6000 cm(-1) at a maximum resolution of 0.06 cm(-1). For many pollutants, concentrations in the 1-10-ppb range can be detected over a 1-km path length. To date, measurements have been made in the absorption mode across fertilizer plant gypsum ponds, an oil refinery, and jet engine plumes; industrial stacks, waste gas flares, and jet engine plumes have been studied in the emission mode.
一套带有望远光学系统的商用傅里叶变换干涉仪已安装在一辆厢式货车中，并用于在多个地理位置进行气态污染物浓度的长路径吸收和单端发射测量。该系统覆盖从650厘米⁻¹至6000厘米⁻¹的红外光谱区域，最大分辨率为0.06厘米⁻¹。对于许多污染物，在1千米的路径长度上可检测到浓度在1至10 ppb范围内的物质。迄今为止，已在吸收模式下对化肥厂石膏池、炼油厂和喷气发动机羽流进行了测量；在发射模式下研究了工业烟囱、废气火炬和喷气发动机羽流。
