Title: E Calvin Johnson: Innovator in Imaging Technology
Introduction
E Calvin Johnson is a notable inventor based in Tampa, FL (US), recognized for his contributions to imaging technology. He holds 2 patents that showcase his innovative approach to enhancing image resolution through advanced mathematical techniques.
Latest Patents
His latest patents include "RF Image Reconstruction and Super Resolution Using Fourier Transform" and "Super-Resolution by Focal Plane Immersion." The first patent employs special mathematical techniques to process accurate energy measurements in the focal plane of a high-quality imaging system, resulting in high-resolution images that exceed the generally accepted Rayleigh limits. This is achieved by adapting Fourier transform techniques and utilizing both in-phase and quadrature components to recover the target scene. The measurement of these components is taken in the focal plane and undergoes parallel processing to preserve both amplitude and phase in the resulting image. A Fourier transform of the aperture characteristics is removed from a Fourier transform of the energy components to yield a Fourier transform of the image, which is then recovered through an inverse Fourier transform.
The second patent focuses on super-resolution by immersing the focal region in a dielectric medium with an index of refraction greater than one. This immersion reduces the size of the diffraction pattern in the focal region, allowing for microwave pictures to be taken at the same resolution as optical pictures using the same aperture size when an appropriate dielectric immersion material is provided.
