The Measurement of the Time of Flash-Light Induced Latent Image Formation
Hiroshi Hada, Mitsuo Kawasaki, Takuji Fukaya · The Journal of Photographic Science · 1985
Ahigh intensity shorl flash-light exposure produces a number of photoelectrons and positive holes in a grain, and starts the processes of latent image formation. A realtime pursuit of the processes is attempted by measuring the Dember elTect with another light flash delayed for various time intervals from the first high intensity flash exposure. The processes of the flash-light II1duced latent image formation continue up to IOO~IS at a room temperature and is gradually prolonged at lower temperatures. InterpretatIon IS given in terms of the aggregation of photolytic silver atoms and the relaxation or deactivation processes of the positive holes.
