Abstract
A system for inspecting a coating on a substrate, the system including a platform that receives a sample including the substrate having the coating, and a light source that directs a plurality of electromagnetic pulses towards a scanning location on the coating, wherein the light source is oriented to direct the plurality of electromagnetic pulses at an oblique angle relative to a surface of the coating. A light detector receives electromagnetic pulses reflected from the sample, wherein a first portion of each electromagnetic pulse is reflected from the surface of the coating, and a second portion of each electromagnetic pulse is reflected from a surface of the substrate. An actuator is coupled to the platform and/or the light source, wherein the actuator moves the platform and the light source relative to each other such that the plurality of electromagnetic pulses are directable towards the scanning location from different rotational positions.
