Title: Innovations of James J Jacob

Introduction

James J Jacob is a notable inventor based in Atherton, CA (US). He has made significant contributions to the field of acousto-optics, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is the "Acousto-optical device with lithium tantalate transducer." This device includes a solid-state substrate that has optical characteristics affected by an acoustic wave. A Z-cut lithium tantalate transducer is coupled to the substrate to induce the acoustic wave. The use of lithium tantalate provides a coupling coefficient and acoustic impedance mismatch, generating a high finesse acoustic standing wave within the substrate. Additionally, it offers low shear wave components with high manufacturing tolerances. This acousto-optical device is also utilized as a high Q modelocker in lasers capable of producing short pulses of laser light.

Another significant patent is the "Star catalog navigation system." In this system, a star pattern within the field of view is transmitted through a non-collinear acousto-optic filter and focused on the input screen of a vidicon. This vidicon is coupled to input storage devices of a computer, each associated with a specific frequency band within the spectrum of light being examined. The contents of these input storage devices are compared with binary data in a star catalog, which contains geometric reference patterns of stars and their frequency signatures. When a correlation signal is produced, an output signal indicating the position of the pattern in the sky can be generated.
