Lensless imaging by spatial Fourier synthesis holography

Not Accessible

Your library or personal account may give you access

Abstract

The technique of Fourier synthesis holography is extended to the spatial domain. A spatially extended source is decomposed into its Fourier components, and a hologram of an object distribution is formed at each spatial frequency and stored in a computer. Upon synthesis in the computer a clear image can be formed of the object without the use of lenses.
