An OpticalFiberBased Airborne Particle Sensor

A new opticalfiberbased airborne particle counter is reported. Unlike traditional lightscatterbased techniques, the particle is detected through the drop in optical fiber coupling efficiency as the particle disrupts the electromagnetic mode of the optical beam. The system is simple, substantially smaller than traditional systems, and does not require high power laser input.
