Abstract

Laser absorption computed tomography offers the possibility of sensitive remote atmospheric measurements of pollutants over kilometer sized areas with 2-D resolution at modest laser source powers. We present detailed model studies which demonstrate the potential of this new remote sensing technique. The tomographic reconstruction process is studied as a function of measurement signal to noise, laser power, range, and system geometry. The analysis shows that the proposed system is capable of providing 2-D maps of pollutant concentration at ranges and resolutions superior to that attainable from contemporary direct detection laser radars.
