Title: Innovations by Elizabeth M C Jones

Introduction

Elizabeth M C Jones is a notable inventor based in Cedar Crest, NM (US). She has made significant contributions to the field of imaging technology, holding 3 patents that showcase her innovative spirit and technical expertise.

Latest Patents

One of her latest patents is related to X-ray digital image correlation. This method involves aligning cameras of an X-ray imaging system, which includes two X-ray sources aimed at a target area at a stereo angle and two corresponding X-ray detectors positioned behind the target area. The system is designed to optimize power levels of the X-ray sources to enhance image contrast and signal-to-noise ratio. It also includes calibration to determine both intrinsic and extrinsic stereoscopic imaging parameters. A specimen with a random contrast pattern is placed in the target area, and stereoscopic X-ray images are captured and processed to maximize image quality while eliminating background objects. Kinematic quantities are derived from changes in the contrast pattern across successive images.

Another significant patent by Jones is the thermographic phosphor digital image correlation. This invention enhances the ratio method of phosphor thermography by utilizing two machine vision cameras for comprehensive temperature measurements of solid surfaces. Algorithms from digital image correlation (DIC) are employed to accurately register material points on the sample to subpixel locations in each image with remarkable precision. The methodology allows for full-field temperature measurements in dynamic tests involving deforming specimens, combining thermographic phosphors with stereo digital image correlation to measure time-resolved full-field surface strains and temperatures simultaneously.
