Compressive Raman microspectroscopy parallelized by single-photon avalanche diode arrays

Abstract

We demonstrate an efficient and scalable compressive Raman parallelization scheme based on single-photon avalanche diode (SPAD) arrays to reach pixel dwell times of 23 $\hat{I}¼$s, representing over 10$\times$ speed-up using the otherwise weak spontaneous Raman effect.
