Title: The Innovative Contributions of Robert L. Hazel
Introduction
Robert L. Hazel is a notable inventor based in Thousand Oaks, California, recognized for his significant contributions to optical memory systems. With a total of 11 patents to his name, Hazel has made remarkable advancements in the field of laser technology.
Latest Patents
Among his latest patents is the "Laser optical memory system having beam combining and separating." This innovative optical memory system utilizes laser beams for reading and writing data on an optical disk. The system features a specially designed spatial combining and separating device that combines a writing laser beam with multiple reading laser beams, allowing for precise focusing on the disk. Additionally, this device separates the reading laser beams from the writing laser beam after reflection, preventing interference from the higher intensity writing beam during the detection of the lower intensity reading beams.
Another significant patent is the "Focus detection and control apparatus for maintaining accurate focusing." This focus detecting apparatus is particularly useful in optical storage systems. It detects the quality of focusing of a laser beam on the surface of an optical medium. The reflected beam is collected and separated into two beams, which are then applied to first and second photosensitive elements. Focus detection is achieved by determining the difference between the diameters of the beams incident on these elements, indicating the quality of the beam's focus on the surface.
