【摘要】 针对常用的激光散斑照相方法在实测中出现较大实验误差影响实用的问题,提出改进方案--双光束散斑照相方法。文中给出了双光束散斑照相方法的理论分析及实测结果,表明改进后的实验方法大大消除了普通散斑照相方法的实验误差,新的实验方法更具实用意义。更多还原

【Abstract】 Presents a new method——double-beam laser speckle photography aiming at the experimental errors in general laser speckle photography which have effected the using in practice.Theoretic analysis and experiental results indicate that experimental errors have been reduced greatly,and so the new method will have more practical value.更多还原
