Photostimulated luminescence
Videos
Photostimulated luminescence is the release of stored energy within a phosphor by stimulation with visible light, to produce a luminescent signal. X-rays may induce such an energy storage. A plate bas

X-ray detectors are devices used to measure the flux, spatial distribution, spectrum, and/or other properties of X-rays.

…induce such an energy storage. A plate based on this mechanism is called a photostimulable phosphor (PSP) plate (or imaging plate) and is one type of X-ray detector used in projectional radiography. Creating an image requires illuminating the plate twice: the first exposure, to the radiation of interest, "writes…
