    Abstract

    To simulate the evolution of spraying/sputtering particle field in spacecraft shield structure material under debris′ hypervelocity impact and obtain its information, a study was made on exploring three-dimensional reconstruction technology of debris′ hypervelocity impact process based on laser holographic images. The holographic image was preprocessed to divide it into 300×300 sub-images and triangular mesh algorithm was applied in sub-images of the stacked area; then the contour of the particle was extracted with Sobel operator and projected into specific space to form three-dimensional shape; the particle field evolution steps were presented based on MAXScript language. The expermental results reveal the validity of this technology, and both static reconstruction results and particle field evolution agree with the expermental images quite well. The method provides a new idea to research the spacecraft shield structure damage effects caused by debries.
