Infrared focal plane arrays (IRFPAs) are essential components in infrared imaging systems, but they often suffer from nonuniformity issues that can degrade image quality. Nonuniformity arises from ...

Huang also explained that nonuniformity in perovskite films arises from oxidized perovskite inks, especially oxidation of iodide to molecular iodine when inks are exposed to an ambient environment ...

Collectively, the spatial variation of the imaging system is caused by a combination of excitation nonuniformity and detection nonuniformity. We have developed a technique to correct illumination ...
