Abstract

The cloud in the high altitude is usually in the gas-liquid mixed state, this paper simulates the environment of the cloud particle using bubble field in the liquid. The paper research the gas-liquid mixture via measuring the size and 3D position of the bubble using a digital in-line holographic imaging system. The design of the optical system and the algorithm of reconstruction, recognition and extraction about the digital hologram is presented. The digital holography deserves to be selected as the projection to measure the bubble field because of advantages such as being able to record and reconstruct the three-dimensional position information, avoiding disturbing the object and insuring the instantaneity during the measurement. The optical system and the algorithm about the digital program have been completed, the hologram of bubbles in the liquids recorded by CCD, the hologram reconstruction using the digital hologram after denoising processing is accomplished. The character of cloud particles can be measured by using holography after analyzing the parameter of the bubbles.
