Abstract

A high speed and high precision time-interval measurement system based on FPGA and TDC-GP21 was introduced in this paper. The high precision module of TDC-GP21 was used and by configuring TDC-GP21

the time-interval measurement and calibration are finished to improve the precision

and a multi-level FSM were designed to realize the SPI communication and reduce the measurement period. According to the analysis of the factors which affected the precision of measure and the drift error of three discriminators

a discriminator was designed to reduce the nonlinearity error of the system. The signal of FPGA and the signal of laser echo were also used to realize time-interval measurement and laser ranging. The experiment results showed that the good linearity and the measurement repetition rate of 1 kHz and the measuring precision of 100 ps can be achieved.
