摘要：

Given the increase in the studies for machining hard and brittle materials with high efficiency and low damage and the lack of effective detection of the machining-induced subsurface damage(SSD), we propose a new method, i.e., polarized laser scattering(PLS), for the detection of subsurface damage in hard and brittle materials. The detection principle was resolved based on the electromagnetic scattering. The critical influence factors, such as surface scattering, residual stress, subsurface damage distribution, etc., were clarified by using PLS method. We tried to applied PLS method to detecting SSD in several materials, e.g., silicon wafer, fused silica. It demonstrates that PLS method is feasible to detect the machining-induced SSD in hard and brittle materials. We provide a new solution to the SSD detection.
