Introduction

G H Hayes is a notable inventor based in Winsted, Connecticut. He has made significant contributions to the field of optical metrology, particularly with his innovative patent that enhances measurement precision.

Latest Patents

Hayes holds a patent for an "Optical thickness profiler using synthetic wavelengths." This optical metrology method and apparatus involves generating and separating three optical wavelengths of fixed polarization into a reference beam and a measurement beam. The measurement beam reflects from the surfaces being analyzed and is combined with the reference beam. Sensors then measure the intensity associated with each wavelength. Any differences in intensity indicate variations in optical path lengths, which can reveal differences in surface characteristics or material properties.
