摘要： A trace species detection System for engine health monitoring, the system including a laser (32) for generating a laser beam (34), and optics for focusing the laser beam into an exhaust plume of an engine for thereby creating a spark in the exhaust plume. The System further includes spectral analysis instrumentation (40) for detecting light emissions from the spark, and statistical processing instrumentation (100) for analyzing data from the spectral analysis instrumentation (40) for thereby identifying and quantifying specific particles within a volume of the spark. The invention also provides a method of monitoring the health of an engine, the method including generating a laser beam, focusing the laser beam into an exhaust plume of the engine for thereby creating a spark in the exhaust plume, detecting light emissions from the spark, and analyzing data from the detection for thereby identifying and quantifying specific particles within a volume of the spark.

摘要： Techniques and devices are disclosed for detecting particle composition. In one aspect, a method performed by a detector to detect particles includes receiving particles at an aerosol inlet of the detector. The method includes carrying the received particles within a stream of gas and charging the particles within the stream of gas using a charger to have a charge. The method includes transporting the charged particles to a location of a collection electrode. The method includes biasing the collection electrode to a voltage using a high- voltage supply to attract either negatively or positively charged particles, and analyzing the particles.
