Title: Tracy Francis Thonn: Innovator in Optical Technologies

Introduction

Tracy Francis Thonn is a prominent inventor based in Sunnyvale, CA (US). She has made significant contributions to the field of optical technologies, holding a total of 4 patents. Her work focuses on enhancing the precision and efficiency of optical systems.

Latest Patents

One of her latest patents is a detection system for optical beam pointing and shaping. This apparatus is designed to circularize an optical beam and direct it into an optical system with mutually perpendicular X, Y, and Z axes. The Z-axis serves as the propagation axis of the beam, while a detector arrangement receives a sample of the optical beam. This arrangement features four detector elements positioned in quadrants defined by the x-axis and y-axis, which are perpendicular to each other. The signals from these detector elements provide critical information regarding the beam's circularity and any displacement in the X and Y axes.

Another notable patent is the turning prism for ultraviolet radiation. This invention involves a truncated triangular prism with an entrance and an exit face that are perpendicular to each other. The reflecting face is inclined at an angle α to the entrance face, where α is approximately 135° - θ, and θ represents the external Brewster angle for the prism material at the specific wavelength of radiation. A beam of p-polarized radiation directed into the prism at the Brewster angle is totally internally reflected and exits at the Brewster angle, maintaining a ninety-degree angle to the incoming direction.
