Title: The Innovative Contributions of William H. Culver
Introduction
William H. Culver is a notable inventor based in Washington, DC, with a remarkable portfolio of eight patents. His work primarily focuses on advancements in imaging technology and optical systems, showcasing his innovative spirit and technical expertise.
Latest Patents
Culver's latest patents include a groundbreaking camera system that combines images of different scene depths. This camera captures two parts of the same scene, each at a different focus, allowing for objects at varying distances to be in sharp focus. The system utilizes a splitter to divide the image into two paths, with each path being focused either manually or through autofocus. The images can be combined at a boundary or in a blending zone using linear or non-linear functions.
Another significant invention is an optical switch designed for optical networks. This switch enables the rapid switching of light beams from input fibers to output fibers without the need for costly intermediate electrical conversions. It operates by altering the relative phase of individual portions of a wave front using wave front interference, achieving switching speeds of approximately 10 nanoseconds. The optical switch employs phase spatial light modulators (PSLM) that consist of an array of phase-shifting elements, which can include Gires-Tournois interferometers.
