Remote Sensing System

Abstract
An infrared remote sensing system for monitoring urban transport emissions has
been developed. This system consists of three main components, i.e., an IR
source, a high sensitivity IR detector, and an electronic data acquisition unit
with in-house computer software. From the Beer-Lambert Law, it was known
that infrared signals from the detector should be influenced by the emission gas
concentrations, the intensity of the source, and the distance between the source
and the detector. In order to operate this remote system over wide varieties of
urban road and the ambient conditions, a series of off-road laboratory
experiments was made with different IR source intensities and different
operating distances between the IR source and the detector. The infrared signal
was a function of the IR source voltage(K),
