Title: Innovations of Susan M Raffensperger
Introduction
Susan M Raffensperger is a notable inventor based in Long Beach, California. She has made significant contributions to the field of laser scanning technology, holding a total of 3 patents. Her work focuses on advancements in lidar applications and holographic optical elements.
Latest Patents
One of her latest patents is the "Laser scanner with peripheral scanning capability." This invention relates to a tilted primary clamshell lens laser scanner designed to transmit a collimated beam of radiation at a first frequency. The beam rotates around a central axis, forming a conical scanning pattern suitable for lidar applications. Additionally, the system transmits at least one more collimated beam of radiation at a second frequency, which operates at a wider angle than the first beam.
Another significant patent is the "Holographic laser scanner and rangefinder." This invention features a holographic optical element (HOE) with a substrate structure that has rotational symmetry. It supports at least two holograms, allowing for the diffraction of a normally incident beam at different angles and in various radial directions. This design enables the achievement of a redirected path that is the difference between the sizes of the angles created by the holograms. The substrate structure may include multiple disc-shaped substrates bonded together, and it may also incorporate thin-film interference filters to suppress zero-order leakage.
Career Highlights
Throughout her career, Susan has worked with prominent companies such as Northrop Grumman Systems Corporation and Northrop Corporation. Her experience in these organizations has contributed to her expertise in laser technology and optical systems.
