Label-free Tissue Imaging With SRS Microscopy (image) Harvard University Share Print E-Mail Caption (left) SRS images of the viable epidermis at the CH3-vibration mainly highlight proteins. A capillary with individual red blood cells (arrow) is visible. The cells are imaged without motion blur due to video rate acquisition speed. (right) An x-t plot acquired by line-scanning across a capillary at the position of the arrow. Individual red blood cells are captured on the fly. Scale: 25 μm.
