Beyond MHz image recordings using LEDs and the FRAME concept

Abstract Many important scientific questions in physics, chemistry and biology rely on high-speed optical imaging techniques for their investigations. These techniques are either passive, relying on the rapid readout of photoactive elements, or active, relying on the illumination properties of speci...
