Partially Coherent Object Length Estimation: Information-theoretic Analysis

Kwan Kit Lee and Amit Ashok

Not Accessible

Your library or personal account may give you access

Abstract

We analyze the fundamental limits of source angular extent estimation for direct imaging and mode-sorting measurements as a function of source coherence length. We demonstrate that mode-sorting outperforms direct imaging in the sub-Rayleigh regime.
