Abstract

3D range-gated imaging with stepping delay is a novel technology developed in recent years. 3D timing control signal based on delay line and logical AND gate technology is proposed innovatively in order to satisfy the distance precision of centimeter of 3D imaging in complex background. 3D timing control signal is produced through FPGA nanosecond timing generation module and picosecond timing adjustment module. Simulation and experiment show that the delay precision of the timing signal designed in this paper is 150 picoseconds, and the narrowest pulse width is close to the limitation of TTL signal (1ns level). The timing control signal designed in this paper can be widely used in 3D range-gated imaging because of its high timing control precision, compact construction and flexible parameter setting. Keywords: range-gated, picosecond, timing control, FPGA, delay line
