A Becquerel-disc phosphoroscope for the measurement of lifetimes in room-temperature phosphorimetry.
A Becquerel-disc phosphoroscope is constructed from a commercially available optical chopper with variable frequency and digital read-out. By use of a continuous source, phosphorescence lifetimes in the range 1-1000 msec can be measured with better than 4% relative standard deviation.
