Research on the design of the plasma characteristic parameter detection system

In orderto study the characteristics of plasma generated by the combustion of propellant,the plasma temperature and electron density were detected by spectroscopic diagnostic method,and the plasma characteristic parameter detection system was designed.Based on the spectral detection method,the design of the sensor,the design of the spectrometer and the data processing were carried out according to the principle of the spectrum analysis and the overall scheme of the detection. Design with ZEMAX to tools, chase trace and fiber optical system design the new sensor optical probe using the optical path of the probe; using a spectrometer structure function optimization,dissipated like processing and wavelength spot diagram analysis method design spectrometer of the initial structure and optimize the structure.Based on the spectrum diagnosis,a set of spectrum detection scheme which can be applied to the combustion of propellants is presented,which provides a basis for further research on the characteristics of the plasma produced by the combustion of propellant.
