Title: The Innovations of David C Grant, Jr.

Introduction

David C Grant, Jr. is a notable inventor based in Thousand Oaks, CA. He has made significant contributions to the field of optical technology, holding a total of three patents. His work primarily focuses on advancements in laser gyroscopes and controllable mirrors.

Latest Patents

One of his latest patents is an optical combiner for a ring laser gyro. This invention features a composite combining prism designed to merge the beams of a ring laser gyro. The apparatus utilizes two substantially identical juxtaposed sub-prisms equipped with beam splitters at their common boundary. These beam splitter regions consist of very thin dielectric films, typically no thicker than a fraction of a wavelength of the laser light. The use of materials like titanium dioxide ensures that the geometrical path lengths of the interfering beams are nearly identical. To achieve optical uniformity, the sub-prisms and the substrate of the partly transmitting corner mirror of the ring laser are designed to have the same index of refraction. In one embodiment, the composite prism has a rectangular cross-section and features two combining light heterodyne sensors. Another embodiment optimizes the design by lying flat on the substrate of the corner mirror, utilizing a forty-five-degree prism surface to redirect the laser light.
