Title: **The Innovative Contributions of Charles C Cheng: A Focus on Optical Technology**
Introduction
Charles C Cheng, based in Cupertino, CA, is an accomplished inventor with a significant portfolio of seven patents to his name. His work primarily focuses on optical technology, aimed at advancing data storage systems through innovative optical solutions.
Latest Patents
Cheng’s latest patent revolves around a high numerical aperture optical focusing device designed for use in data storage systems. This optical focusing device effectively focuses an incident optical beam onto a focal plane to create a precise focal spot. It features a conical central refractive facet where the optical beam impinges, and a high-index glass body through which the beam travels toward a bottom reflective surface. The reflective surface directs the optical beam towards a peripheral reflector that concentrates the beam into a defined focal plane situated on a pedestal extending from the reflective surface. This device incorporates a conically shaped central facet which refracts the beam, while the peripheral reflector—which may take various appropriate shapes such as aspherical or tilted parabolic—compensates for optical aberrations created by the conical design. The device's top surface, consisting of both the central and peripheral facets, can be fine-tuned using diffractive optical elements or Fresnel optics. Furthermore, the focal spot can be optimized utilizing sequential quadratic programming and a set of bespoke coefficients, showcasing Cheng's commitment to precision in optical design.
