Title: The Innovative Contributions of Bruce G. MacDonald
Introduction: Bruce G. MacDonald, an accomplished inventor based in San Diego, California, has made significant strides in the field of material processing technology. With a total of six patents to his name, his work focuses on the utilization of advanced laser technologies for manufacturing applications.
Latest Patents: Among Bruce's latest innovations is a patent titled "Use of Fresnel Zone Plates for Material Processing." This innovative apparatus integrates an excimer laser with a Fresnel zone plate array (FZP) positioned parallel to the workpiece. The design allows for precision machining by ensuring that the distance between the FZP and the workpiece is maintained at the focal length of the FZP. For each hole to be created on the workpiece, a corresponding Fresnel zone is meticulously patterned onto the FZP. These zones can be aligned directly over the intended hole or configured in high-density patterns that allow for off-center operations, achieved by manipulating finely crafted circular arcs on the Fresnel zone. A beam scanner enhances the uniformity of illumination, while an alignment mechanism utilizing a helium-neon laser accurately projects onto the surface relief grating of the workpiece, resulting in maximum light intensity through a transmission grating on the Fresnel zone plate.
Career Highlights: Bruce's tenure at Litel Instruments has been marked by his commitment to advancing laser processing technology. His innovative solutions have not only demonstrated his inventive prowess but have also contributed to the overall effectiveness of material processing methods within his industry.
