The dynamic properties of rotating symmetrical targets with visible band laser are analyzed and the time sequence speckle optical system to measure multi-pose rotating targets is designed,with the aim at the characteristics recognition of line-of-sight angle and angular velocity for rotating targets,on the basis of the laser scattering theory.The results reveal that the curve of normalized time correlation function can be achieved by adopting multi-map time correlation function algorithm,for dynamic speckles at different line-of-sight angles and angular speeds; the relationship is obtained of time statistical properties with line-of-sight angle within 20°-90° and angular speed within 0.5r/min-6r/min.
