Abstract

A simple implementation of the stroboscopic optical boxcar technique for determining intensity profiles of repetitive nanoseconds light pulses is presented. The device, implemented with standard components and a 1P28 photomultiplier tube, can be used for fluorescence decay measurements with subnanosecond time resolution.
