Serial time-encoded amplified microscopy

Time stretch microscopy, also known as serial time-encoded amplified imaging/microscopy or stretched time-encoded amplified imaging/microscopy' (STEAM), is a fast real-time optical imaging method that provides MHz frame rate, ~100 ps shutter speed, and ~30 dB (× 1000) optical image gain. Based on the photonic time stretch technique, STEAM holds world records for shutter speed and frame rate in continuous real-time imaging.
