Inspection Systems and Methods Employing Different Wavelength Directional Light For Enhanced Imaging

An inspection system and related methods are provided. The inspection system includes an inspection camera, a plurality of light sources collocated with the inspection camera, and a post processing system. The plurality of light sources output directional light that have different respective ranges of light wavelengths. The inspection camera is configured to capture image data while a surface of interest is being illuminated with the directional light. Further, the post processing system is configured to receive the image data, process portions of the image data into a plurality of images that include distinct images corresponding to the different respective ranges of light wavelengths. The plurality of images can be reviewed to identify an abnormal region of the surface of interest.
