Engine tail jet particulate matter parameter monitoring device

According to the engine tail jet flow particulate matter parameter monitoring device, by simultaneously measuring scattered light and radiant light of high-speed tail jet flow particles, parameter analysis and source identification of particle size, concentration, components and the like of the engine tail jet flow particulate matter and radiation parameter algorithms of radiation temperature, radiance, radiation intensity and the like are established; parameters and sources such as particle size, concentration and components of the tail jet flow particulate matter and radiation parameters such as radiation temperature, radiance and radiation intensity are synchronously monitored, meanwhile, a three-dimensional image is rapidly triggered to measure and capture a three-dimensional image ofthe particle, the three-dimensional size and surface morphology of the particle are further determined, and the particle source is defined; therefore, the working safety state of the engine is evaluated through the parameters
