Team applies fiber optics instead of lenses to open a new horizon of super-resolution photoacoustic microscopes

by Pohang University of Science & Technology (POSTECH)  A microscope system that uses optical fibers instead of lenses. Credit: POSTECH Newly developed photoacoustic microscopy uses vibrations generated when light is absorbed and captures images of cells or blood vessels. This development has increased the possibility of peering inside the body without contrast agents. However, obtaining...
