Towards Video-Rate Compressive Spontaneous Raman Imaging Using Single-Photon Avalanche Diode Arrays (Invited Paper)

9 April 2024 • 10:00 - 10:30 CEST | Etoile B, Niveau/Level 1

Abstract

Compressive Raman imaging has emerged as a promising technique to speed up chemical imaging by compressing the data during acquisition. Yet, current scanning imaging speed is fundamentally limited by the sensors pixel dwell times of at best 1µs. Here, we introduce a compressive Raman spectrometer layout equipped with a novel parallelized spatial acquisition using a single-photon avalanche detector array. We show imaging with pixel dwell times of <10µs using the otherwise weak spontaneous Raman effect, thereby unlocking video-rate imaging.
