Title: **Innovative Contributions of Donald K. Cohen**
Introduction
Donald K. Cohen, a prominent inventor based in Tucson, AZ, has made significant contributions to the field of technology with a total of 11 patents. His work focuses on advanced methods of profiling rough surfaces of objects, showcasing his expertise and innovative mindset.
Latest Patents
One of Cohen's latest patents, titled "Rough Surface Profiler and Method," outlines a novel approach to profiling irregular surfaces. The method involves moving the object along a z-axis to align the highest point of the surface optically outside the focus range of a solid-state imaging array. Using a two-beam interferometer, an interferogram of the rough surface is generated, and the solid-state imaging array scans the surface along the x and y axes. This process produces intensity data for each pixel across multiple frames, each shifted by a predetermined phase difference. The method computes the modulation for each pixel and compares it with a previously stored value, thus ensuring optimization. This procedure continues until maximum modulation values and corresponding relative heights are obtained and stored for each pixel.
