Abstract：Based on S-R decomposition theorem and Fourier optical theory, a new technique using computer to analysze laser spectral images of finite deformation automatically was put forward. Firstly, a quantitative relation about finite deformation and geometrical parameters which exhibit variation of laser spectral image was introduced. And then, particular emphasis was put on some important computer processing steps related to the analysis of spectral image, such as digitizing, segmentation, feature extraction and analytical algorithms. Lastly, some examples about an experiment of a ring subject to large diametral compression were given. The research result indicates that this new technique is quite suitable for measurment of finite deformation.
