Title: Joseph Jasperson Shaffer: Innovator in Optical Technology
Introduction
Joseph Jasperson Shaffer is a notable inventor based in Ridgecrest, CA (US). He has made significant contributions to the field of optical technology, holding a total of 4 patents. His innovative work focuses on advanced mirror technologies that enhance optical performance.
Latest Patents
One of Shaffer's latest patents is for a transfer optic mirror. This mirror is designed to be thin enough to allow for small influence functions for surface changes, utilizing cynate ester composites. The mirror is shaped by a series of piezoelectric actuators connected to push/pull rods that are evenly distributed across the back surface. This design ensures that the mirror maintains its shape despite external temperature changes, as it is supported by a material with the same coefficient of expansion. The actuators are controlled by a computer, allowing for precise contouring of the mirror as needed.
Another significant patent is for an adaptive optic mirror. This mirror features a cyanate faceplate supported by a backplate, which allows multiple actuators to be directly connected to the faceplate. Each actuator operates through a low impedance circuit linked to a master control, enabling independent adjustments to create a contoured mirror surface.
