Abstract:
An apparatus for measuring the optical absorption of airborne matter or other light absorbing species in a sample airflow. The apparatus comprises a flow path through a fibrous filter to collect light absorbing species in the sampled air. The filtered airflow may subsequently pass through a second filter, used for reference measurements. At least one light source impinges in the filter generating one or two optical signals to determine the light absorption of particulate matter or other species in the sampled airflow. The apparatus includes at least one auxiliary sensor in the sample flow path to monitor an environmental factor, such as temperature. During a training period, a mathematical model of the apparatus' environmental sensitivity is derived. Using the mathematical model and measurements from the auxiliary sensor, optical signals are compensated in real time to increase the precision and accuracy of light absorption measurements recorded under fluctuating environmental conditions.

Claim (Index 15):
The apparatus of  claim 9  in which said first and second signals each comprises a voltage signal and said comparator means further comprises:\n an analog-to-digital convertor for receiving said first and second voltage signals and generating corresponding first and second digital signals; and \n a microcontroller unit for receiving said first and second digital signals from said analog-to-digital converter and determining the quantity of light absorbing matter in the air sample.
