Abstract

The time-interval measuring systems for timeresolved spectroscopy are discussed in this paper. For instance, for time-of-flight (TOF) spectrometry or lifetime decays measurement applications a simple gated counting system (boxcar), a real-time multichannel scaler (RTMS) or a time-interval interpolator is used. We present the new highresolution (RTMS) system for an intensity function measurement. In this system, the digital tapped delay lines are used. These system with 1,0 ns and 0,5 ns resolution, with tapped delay lines implemented in the structure of the complex programmable logic device FLEX10K 30E are presented.
