Title: Harold Earl Bennett: Innovator in Optical Technology
Introduction
Harold Earl Bennett is a distinguished inventor based in Ridgecrest, California, known for his contributions to optical technology. With a total of six patents to his name, Bennett has made significant advancements in the field, particularly in the development of innovative optical devices.
Latest Patents
One of Bennett's latest patents is for a transfer optic mirror. This thin mirror is designed to allow small influence functions for surface changes and is constructed from cyanate ester composites. The mirror is shaped by a series of piezoelectric actuators connected to push/pull rods that are evenly distributed across the back surface. This design ensures that the mirror maintains its shape despite external temperature changes, as it is supported by a material with the same coefficient of expansion. The actuators are computer-controlled, allowing for precise contouring of the mirror as needed.
Another notable patent is a device to control laser spot size. This invention utilizes a fixed-size laser beam to illuminate a solar array, maintaining a constant beam spot size even when the distance to the array varies significantly. The focal point of the mirror emitting the beam is adjusted to ensure that the desired beam waist is consistently incident on the array. Additionally, a centering device is attached to the array to ensure that the beam spot is accurately directed.
