Paper Abstract

Atmospheric aerosol refers to the stable mixing system composed of solid and liquid particles evenly dispersed in the atmosphere, and the particles are collectively referred to as aerosol particles. Aerosol particle detection is an important aspect of environmental monitoring. With the development of computer technology and holographic technology, the resolution of holographic measurement technology continues to improve. At present, digital holography can be used to measure the tiny displacement, deformation and vibration of opaque objects. In this paper, aluminum oxide powder is used to simulate aerosol particles. Aerosol particles are recorded by digital holography and holograms of aerosol particles are obtained. Finally, the shape and size of aerosol particles can be obtained.
