||Imaging indoor tracer-gas concentrations with computed tomography: Experimental results with a remote sensing FTIR system
||May 1994, Vol.55, No.5, p.395-402. Illus. 29 ref.
||To show that computer tomography (CT) is a useful tool for investigating pollutant concentration in a real room setting, a remote-sensing Fourier transform infrared spectrometer was mounted on a moving base and a passive tracer was released from a point source into the room under constant ventilation conditions. The experiments produced two data sets, one consisting of 36 beam-path-averaged values and the other consisting of 44 point values from the FID array. Good qualitative agreement between reconstruction and point sample data was obtained. Problems of temporal resolution, size and geometry can be overcome with better instrumentation.
