Researchers at Caltech have developed a new imaging system, phase-sensitive compressed ultrafast photography (pCUP), that combines with phase-contrast microscopy, that was designed to allow better imaging of objects that are mostly transparent such as cells. They adapted the standard phase-contrast microscopy so that it provides very fast imaging. The system consists of lossless encoding compressed ultrafast technology (LLE-CUP) which takes a single shot, capturing all the motion that occurs during the time that shot takes to complete. LLE-CUP is capable of capturing motion, such as the movement of light itself. They demonstrated the capabilities of pCUP by imaging the spread of a shockwave through water and of a laser pulse traveling through a piece of crystalline material. They expect pCUP to be broadly used for a vast range of fundamental and applied sciences, in many fields, including physics, biology, or chemistry…read more. Open Access TECHNICAL ARTICLE
