Introduction

Kerry Bagw Ell is a notable inventor based in Campbell, CA (US). She has made significant contributions to the field of interferometry, particularly with her innovative patent that addresses beam walk-off issues.

Latest Patents

Kerry holds a patent for an "Interferometer using beam re-tracing to eliminate beam walk-off." This invention allows an interferometer to return parallel beams that are subject to walk-off caused by reflector misalignment. By enabling an additional pass through the interferometer optics, her design effectively eliminates beam walk-off. The return reflector can be a plane mirror that directs returning beams to retrace their paths through the interferometer optics, combining and exiting along the axis of the input beam. Additionally, separation optics can separate the combined beam from the input beam. Alternatively, a return reflector such as an isosceles prism or a trapezoidal prism reflects and offsets returning beams, ensuring that the combined beam is offset from the input beam. This innovative approach allows the return reflector to respond to shifts in incident beam position with a matching shift of the reflected beam, contrasting with a retroreflector that shifts a reflected beam in the opposite direction.
