Title: Joseph J Purrazzella: Innovator in Optical Tracking and Laser Technology

Introduction

Joseph J Purrazzella is a notable inventor based in Southampton, NY, recognized for his contributions to optical tracking systems and laser technology. With two patents to his name, Purrazzella has significantly impacted his field through innovative designs and methodologies.

Latest Patents

Purrazzella's recent patents include a high-resolution extended field-of-view tracking apparatus and method, which involves an optical tracking system featuring a scanning mirror. This system captures and processes images within its field of view and utilizes a charge coupled device (CCD) camera for image analysis. The Inertial Measurement Unit (IMU) beam acts as a reference point to determine the position of the scanning mirror. The inclusion of a dispersive element generates a grid pattern of light, allowing for precise centroiding of the diffracted orders related to the scanning mirror's position.

Another notable patent addresses an optical combiner for a ring laser gyro. This invention features a composite combining prism made from two identical sub-prisms with dielectric beam splitters at their boundary. These thin films ensure that the geometrical path lengths of the interfering beams remain virtually identical, enhancing the system's accuracy. The design includes both a rectangular cross-section prism and a more compact version that lies flat on the substrate of the corner mirror, demonstrating versatility in application.
