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 16):
An apparatus for determining the optical absorption of matter in an air sample, comprising:\n a case, said case forming a chamber therewithin; one filter positioned within said chamber, said air sample passing through said one filter; another filter, said air sample passing through said another filter subsequent to passage through said one filter. a light source directing light through said filter; said light source comprising; a first light source; and a second light source; said first light source directing light to pass through said one filter and said second light source directing light to pass through said another filter; a light detector for alternately receiving light from said first and second light sources, respectively, passed through said one and another filters, respectively, and generating at least a first signal; a temperature sensor for providing a second signal for adjusting said first signal; and a means for comparing said first signal to a subsequent signal from said light detector.
