We present a novel ultrafast imaging system using Spatio-Temporal Optical Coherence Tomography (STOC-T), capable of acquiring structural images of a mouse retina at a volumetric rate of 112 Hz, aided by a calibrated fundus camera for focal plane adjustment. We extract blood pulse traces from retinal and choroidal vessels using a structural-only OCT analysis, and pulse wave-induced retinal layer displacement from differential OCT phase analysis. With both analyses, we measure hemodynamic parameters, such as the delays between arterial and venous pulsation, to provide a comprehensive suite of potential biomarkers of retinal diseases.
