The validity of expressions for the position of the plane of stationarity, apparent speed of speckle movement, and estimated observer ametropia is examined for laser refraction, using a cylindrical drum. The agreement between theory and experiment is satisfactory. It appears unlikely, however, that methods of subjective refraction depending on estimation of speckle velocity can match the accuracy and precision of those based on rendering the plane of stationarity conjugate with the observer's retina. Even with experienced observers, refractive values based on estimates of speckle speed showed the unsatisfactorily large standard deviation of approximately 0.5 D.S.
使用圆柱形鼓对激光折射中关于平稳平面位置、散斑运动视在速度和估计观察者屈光不正的表达式的有效性进行了检验。理论与实验之间的一致性令人满意。然而，依靠散斑速度估计的主观验光方法似乎不太可能与基于使平稳平面与观察者视网膜共轭的方法的准确性和精度相匹配。即使是经验丰富的观察者，基于散斑速度估计的屈光值也显示出标准差约为0.5 D.S，大得不尽人意。
