Abstract
The in-situ investigation of interstellar dust has becoming one of the focuses in deep space exploration. It is of great importance since it provides us with key information about the origin and evolution of planets. To measure the size of a single slow dust particle, a laser-based optical measurement system was designed and calibrated accordingly. In this system, a detection area of 50mm*50mm laser curtain was generated using a diffractive optical element (DOE) and a cylindrical lens, which transform the laser beam in Gaussian profile to a laser sheet with a rectangular uniform profile. When a dust particle passes through the laser curtain, scattered light will be generated and collected by a compound parabolic concentrator (CPC) and then be converted into an electrical signal by a PIN photodiode. The amplitude of electrical signals, which are directly related to the scattered light flux, are used to extract the particle size. Standard spherical SiO2 sample particles of different sizes were used in the calibration activities. Satisfied agreements have been achieved between the theoretical result calculated using the Lorenz-Mie theory and the experimental result.
