A Multi‐Resonant Tunable Fabry‐Pérot Cavity for High Throughput Spectral Imaging
Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This study introduces a multi‐resonant tunable Fabry‐Pérot filter for high throughput spectral imaging. With a spectral resolution of 10 nm and a switching time of 23 ms, this compact and low‐cost device possesses better spectral imaging accuracy in poor light conditions while maintaining over six times higher optical throughput than standard liquid ...
