Title: The Innovative Contributions of John D. Redmyer

Introduction

John D. Redmyer is a notable inventor based in Columbus, Ohio. He has made significant contributions to the field of optical gauging devices. His innovative work has led to the development of a unique patent that enhances measurement accuracy.

Latest Patents

Redmyer's most recent patent is for a Reticle Calibrated Diameter Gauge. This non-contact optical gauging device utilizes a laser beam that is deflected to produce a bidirectional scan. The device features a split beam; one portion scans the object being inspected while the other scans a calibration reticle with alternating opaque and transparent bands. The alternating transmission and occlusion of the beam through the reticle generate calibration pulses, which represent predetermined increments of movement. The occlusion of the measuring beam by the object generates a signal that controls the counting of calibration pulses, indicating the dimension being measured. Bidirectional averaging is employed to minimize errors caused by object motion during the scanning process.
