HOLOGRAPHIC IMAGING WITH IMPROVED SNR

Document Type and Number:

WIPO Patent Application WO/2017/120414

Kind Code:

A3

Abstract:

An apparatus for holographic imaging includes first and second image planes, and a low-pass filtering stage between them. The low-pass filtering stage has a mask disposed to remove a central portion of an interference pattern on the first image plane. This causes a filtered interference pattern to be incident on the second image plane.
