Abstract
The developed method is used for subsurface damage evaluation. It is based on CNC subaperture asymmetric polishing of the surface, which leads to the formation of a wedge with decreasing depth, depending on the diameter and a subsequent analysis of the surface using White - Light Interferometry. In the evaluation, 'negative PV value' method was used enabling the detection of the depth of damage with the accuracy of 1 micron.
