Title: Innovations of Timothy J Edwards
Introduction
Timothy J Edwards is a notable inventor based in Hermosa Beach, CA. He has made significant contributions to the field of holography, holding a total of 3 patents. His work focuses on improving the quality and efficiency of hologram formation.
Latest Patents
One of his latest patents is titled "Systems for forming improved reflection holograms with a single beam." This invention describes a hologram forming system that utilizes a single beam source and a reflective mirror to create a reflective hologram. The system effectively eliminates spurious reflection and transmission hologram recordings by changing the phase of reflected rays relative to the primary beams during the recording period. This innovation results in a slight change in the overall refractive index of the recording material, which can affect the modulation index or contrast of the hologram.
Another significant patent is "Double beam systems for forming improved holograms." This system employs two beams to form enhanced reflection and transmission holograms while eliminating higher energy spurious holographic recordings caused by reflections from the cover plates. The invention includes mechanisms for moving the cover plate or the substrate and recording medium during the recording period to prevent unwanted recordings. Additionally, global phase shifters are utilized to maintain the phase of the primary rays at a high level.
