Abstract

We propose a time domain speckle contrast optical spectroscopy (SCOS) system that makes use of a gated detector and pulsed light source to measure the blood flow variations at very short, quasi-null (<3mm) source-detector separation. We present the results of a human arm cuff occlusion and a comparison with standard SCOS, highlighting that we can probe deeper into tissue, reduce probe footprint, make efficient use of the signal and decrease cost.3
