Title: Innovations of John J Hizny
Introduction
John J Hizny is a notable inventor based in North Billerica, MA, who has made significant contributions to the field of optical devices. With a total of two patents to his name, Hizny's work focuses on enhancing the functionality and efficiency of optical systems.
Latest Patents
Hizny's latest patents include the "Monolithic Laser Spatial Filter" and the "Optical Wavefront Sensing System." The Monolithic Laser Spatial Filter is an innovative optical device that utilizes a GRIN rod with a centered aperture. This design allows for the coupling of laser radiation through a spatial aperture while minimizing alignment sensitivity issues that are common in prior art. The output beam from this spatial filter is primarily affected by vignetting due to misalignment, rather than the distorted wavefronts that were characteristic of earlier designs.
The Optical Wavefront Sensing System is another groundbreaking invention by Hizny. This system detects distortions in light wavefronts by dividing the wavefront into multiple subapertures. The light from each subaperture is amplified and imaged as spots onto a filter mask. This mask encodes a predetermined function of the spot intensity distribution, allowing for effective spot centroid calculations. The mask can include various embodiments, such as linearly varying chevrons and electronically variable chevrons.
