Abstract
We propose to develop a "black carbon" (soot) monitor for measuring non-volatile particulate emissions from gas turbine engines employing a proprietary optical extinction measurement technique based on cavity attenuated phase shift spectroscopy (CAPS) operting in conjunction with a differential mobility analyzer. The singular aspect of the CAPS approach is that extinction is measured by determining shifts in the phase angle of a modulated light beam instead of changes in the intensity of the ransmitted light caused by the presence of particulates. This aspect makes the sensor immune to either abrupt or gradual changes in the intensity of the light caused by temperature or pressure fluctuations or light source deterioration. Furthermore, the sensor rarely needs to be calibrated
