Abstract

Electro-optical sensors measure energy transmitted by lasers spaced about a region’s periphery. Both the lasers and sensors are tuned to infrared frequencies at which air pollutants strongly absorb electromagnetic energy. The sensor measurements are processed using an algorithm derived from the Radon transform. The result is an estimate of air pollutant density throughout the region that has been smoothed to minimize effects due to background sunlight fluctuations, laser fading and phase scintillation, and intrinsic sensor noise. Good agreement is found between a theoretical analysis of performance limitations and computer simulation results
