For detection systems that record discrete events, such as particle and nuclear detectors, the dead time is the time after each event during which the system is not able to record another event. An everyday life example of this is what happens when someone takes a photo using a flash - another picture cannot be taken immediately afterward because the flash needs a few seconds to recharge. In addition to lowering the detection efficiency, dead times can have other effects, such as creating possible exploits in quantum cryptography.

Famous quotes containing the words dead and/or time:
“The five kings count the dead but do not soften
The crusted wound nor stroke the brow;
A hand rules pity as a hand rules heaven;
Hands have no tears to flow.”
—Dylan Thomas (1914–1953)
“When I saw it I was so glad I could not speak. My eyes seemed too little to see it all.... I was a long time without speaking to my friend. To see me always looking and never speaking he thought I had lost my mind. I could not understand where all this could come from.”
—For the State of Maine, U.S. public relief program (1935-1943)
