Title: James M Howell: Innovator in Optical Technologies
Introduction
James M Howell is a notable inventor based in Hudson, MA (US), recognized for his contributions to optical technologies. He holds two patents that showcase his innovative approach to beam steering and signal processing.
Latest Patents
One of Howell's latest patents is the Optical Time Delay Apparatus. This invention features an optical time delay unit designed for use in an optical phased array beam-steering system. It includes a switchable polarization rotator, Brewster plates, and mirrors to create electrically-selectable optical paths of varying lengths. The polarization rotator is aligned with the optical beam and responds to control signals to adjust the polarization of light. The Brewster plates allow light to pass through while reflecting other polarizations, enabling the recombination of different paths at a second Brewster plate. This design allows for cascading multiple time delay units to select from various optical paths.
Another significant patent is the Adaptive Beam Forming Apparatus. This device consists of multiple beam ports that generate differently directed beams. One beam targets a desired signal source, while others focus on interfering signals. A processor combines the signals from these ports to enhance the power ratio of the desired signal over the interfering signals. The apparatus effectively cancels out unwanted interference, improving the clarity of the desired signal.
