Title: Innovations by Jim P. Lee: Pioneering Acousto-Optic Signal Processing

Introduction

Jim P. Lee, an accomplished inventor based in Nepean, Canada, has made significant contributions to the field of acousto-optic signal processing. With two patents to his name, Lee's work exemplifies the intersection of innovation and practical application in modern technology.

Latest Patents

Lee's latest patents encompass groundbreaking technology in the acousto-optic domain. His first patent describes a modified multi-channel Bragg cell that employs a phased array structure, designed for high signal reception efficiency in interferometric acousto-optic signal processors. This invention involves a block of acousto-optic material illuminated by a laser beam on one surface, while a series of electroacoustic transducer sets mounted on the opposite surface respond to signals from various antennas. The resulting acousto-optic modulation allows for a two-dimensional display that visualizes the power spectrum of antenna outputs relative to incoming electromagnetic wavefronts.

The second patent introduces a two-dimensional acousto-optic signal processor utilizing a circular antenna array. This innovation enables a 360-degree field of view, using a Butler matrix to connect each antenna element. The signals undergo phase shifting within the matrix before engaging with a multi-channel periodic Bragg cell, culminating in the generation of acoustic waves and subsequent modulation of an illuminating laser beam. Focused by a Fourier transform lens, this diffracted beam characterizes input signal power spectrum and angle of incidence, achieving high resolution that remains consistent across frequencies.
