Title: Chester S. Gardner: Innovator in Optical Measurement and Pupillary Response
Introduction
Chester S. Gardner is a notable inventor based in Champaign, Illinois. He has made significant contributions to the fields of optical measurement and physiological response analysis. With a total of 3 patents, Gardner's work has advanced the understanding of pupillary responses and the measurement of curvilinear surfaces.
Latest Patents
One of Gardner's latest patents is a method and apparatus for determining pupillary response parameters. This invention focuses on measuring parameters such as latency, time of acceleration of constriction, and speed of constriction. The method involves deriving a signal that represents pupil size over time after exposure to a visible light stimulus. The signal is then modified to eliminate artifacts caused by eye movement, allowing for accurate measurement of pupillary response parameters.
Another significant patent is an optical straightness gauge and method. This apparatus is designed to measure the profile of a curvilinear surface. It includes a light source that delivers radiant energy along an illumination plane tangent to the surface. The system blocks a portion of the radiant energy with an optical field stop, while the remaining energy is focused on a transducer. This transducer generates a coded data signal that is processed to determine deviations from a reference profile, facilitating 100% inspection in production environments.
