An optimization design process of the aerosol with good infrared scattering properties is introduced.First, according to the expression of the scattering field of the particles, the optical performance parameters of several particles are calculated, and then the influence of the aerosol on the specific The maximum attenuation value of the infrared wavelength of the incident wavelength.The article finally gives the absorption spectrum of a certain proportion of the aerosol material after processing and mixing and the interference curve to a certain type of thermal imager.The result has reached the predetermined requirement Obviously, the use of aerosols in these particles to shield the infrared will be of great value.
