Abstract
An apparatus for detecting particles in a sample of gas is disclosed. The apparatus comprises a single optical radiation source, a sensor head, and detection electronics. The sensor head comprises a housing having an elliptical cross section. The sensor head receives optical radiation from the source through a fiber optic line at the first focus, and a detector is located at the second focus. The detector receives radiation scattered and emitted by particles in the light beam at the first focus. The detection electronics determine the presence, and in one embodiment the identity, of particles based on the radiation incident on the detector.
