Another excellent result posted to the arXiv today! We replace the mirror in our methane sensing nonlinear interferometer with paper, and it can still sense the background methane in the room and is more robust to misalignment! arxiv.org/abs/2506.17107 @qetlabs.bsky.social @qusit.bsky.social
Open-Path Methane Sensing via Backscattered Light in a Nonlinear Interferometer
Nonlinear interferometry has widespread applications in sensing, spectroscopy, and imaging. However, most implementations require highly reflective mirrors and precise optical alignment, drastically r...
