摘要
观察了当相干激光以不同入射角照射 4个等级的平磨和外圆磨样块时记录的散斑图像中散斑强度的变化。通过分析可知对比度与表面粗糙度之间存在密切的关系 ,入射角又直接影响对比度 ,不同的入射角适合不同的加工方法和测量范围。
Incidence angle has some influences on the speckle intensity. According to the observation on the changes of speckle intensity, irradiated by laser from different incident angles to 4 level flat lapped and ground samples, it brings the result that the incidence angle is changed in different measurement range and a reasonable incidence angle may improve the precision and range of measurement.
