Title: METHOD AND APPARATUS FOR CONTROLLING A PRODUCTION PROCESS
Abstract:
A method of controlling a production process includes illuminating a portion of a workpiece undergoing a production process with a light having a selected wavelength, processing a portion of the workpiece, capturing a digital image of the light reflecting from a surface of the workpiece with a digital camera, performing, with a processor, a specular reflectance analysis of the digital image, and adjusting a production process parameter based on the specular reflectance analysis.
