Fourier Imaging System Applications
PI Jonathan Campbell
This is a line of research encompassing multiple system applications including imaging the sky and Sun in hard x-rays (Astrophysics); imaging terrorist nuclear weapons from UAV's; and medical imaging.
The sky contains many active sources that emit X-rays, gamma rays, and neutrons. Unfortunately, hard X-rays, gamma rays, and neutrons cannot be imaged by conventional optics. This obstacle led to the development of Fourier imaging systems. In early approaches, multiple grid pairs were necessary in order to create rudimentary Fourier imaging systems. At least one set of grid pairs was required to provide multiple real components of a Fourier derived image, and another set was required to provide multiple imaginary components of the image. It has long been recognized that the expense associated with the physical production of the numerous grid pairs required for Fourier imaging was a drawback. This study seeks to use technology application in looking for cancerour cells. The extremely short wavelength offers the promise of finding tumors at smaller sizes (hence more treatable) than other currently available detection methods.
