Noise Resilient Real-time Phase Imaging via Undetected Light

This article reports on a new method for real-time phase imaging that is resilient to noise. The use of 'undetected light' suggests a potentially novel approach, possibly involving techniques like ghost imaging or similar methods that utilize correlated photons or other forms of indirect detection. The source, ArXiv, indicates this is a pre-print or research paper, suggesting the findings are preliminary and haven't undergone peer review yet. The focus on 'noise resilience' is important, as noise is a significant challenge in many imaging techniques.
