ABSTRACT:
A method for inspecting an object using a structured light measurement system that includes a light source and an imaging sensor. The method includes emitting light from the light source, polarizing each of a plurality of different wavelengths of the light emitted from the light source at different polarization angles, projecting light emitted from the light source onto a surface of an object, receiving light reflected from the object surface with the imaging sensor, and analyzing the light received by the imaging sensor to facilitate inspecting at least a portion of the object.
