Time to Digital Converters (TDC)

TDC is the time interval measurement instrument. It is also known as a Time-Of-Flight digitizer. TDC records the time-stamp of input pulses. High resolution TDC is used in particle physics in Time-Of-Flight problem, when particle flight time is measured and it's mass may be calculated. TDC is also used in laser ranging instrument LIDAR.
