Title: Innovations of Philip R Hemmer

Introduction

Philip R Hemmer is a notable inventor based in Fitchburg, MA (US). He has made significant contributions to the field of imaging technology, holding a total of six patents. His work primarily focuses on reducing optical noise in imaging systems, particularly in light scattering mediums.

Latest Patents

One of Hemmer's latest patents is titled "Imaging in a scattering medium using photon density waves." This invention addresses the challenge of optical noise caused by light scattering when examining objects embedded in a scattering medium. By utilizing a modulated signal laser beam and a coherent modulated reference beam, Hemmer's method produces a hologram in a photorefractive member, allowing for the retrieval of a clear image of the object. Additionally, a smart pixel image converter light valve can be used as an alternative to the photorefractive member.

Another significant patent is "Homodyne and heterodyne imaging in a light scattering medium." This invention further reduces optical noise by employing a two-dimensional all-optical phase-sensitive holographic detector. By vibrating the light scattering material at an ultrasonic frequency, Hemmer's technique generates both signal and noise sidebands. The use of homodyne and heterodyne techniques enables the filtering of unwanted noise, resulting in a clear image of the object.
