Demonstration of Dynamic-Range Expansion by ADRIFT-QPI

Caption

Images of silica beads taken using conventional quantitative phase imaging (top) and a clearer image produced using a new ADRIFT-QPI microscopy method (bottom) developed by a research team at the University of Tokyo. The photos on the left are images of the optical phase and images on the right show the optical phase change due to the mid-infrared (molecular specific) light absorption by the silica beads. In this proof-of-concept demonstration, researchers calculated that they achieved approximately 7 times greater sensitivity by ADRIFT-QPI than that by conventional QPI.
