Title: The Innovations of Jeffrey H Everson
Introduction
Jeffrey H Everson is a notable inventor based in Reading, MA (US). He has made significant contributions to the field of photodiode technology, holding 2 patents that showcase his innovative approach to electronic testing and wavefront sensing.
Latest Patents
One of his latest patents is titled "Apparatus and method for contactless characterization of photodiode." This invention provides a noncontact and nondestructive method for testing a photodiode array. The apparatus includes a Surface Acoustic Wave (SAW) device with sets of interdigital finger pairs, which are strategically placed to confine the SAW test probe signal to the diodes being tested. This innovative design allows for the calculation of individual detector properties, such as the zero voltage bias resistance of each detector.
Another significant patent by Everson is the "Wavefront sensor using a surface acoustic wave diffraction grating." This invention is designed to detect the slope of an input wavefront. It utilizes a surface acoustic wave reflective diffraction grating positioned at the wavefront's focal point, generating surface acoustic waves at two primary frequencies. The resulting AC shearing interferogram is detected by a photodetector array, providing valuable information about the local slope of the wavefront.
