Abstract


The papers by pulsed laser ranging time interval measurement technology , design a high-precision time interval measurement system and produced a time interval measurement experimental device . Time measurement accuracy of 100ps, corresponding to 1.5cm range accuracy . This paper first describes the time interval measurement method is usually used at home and abroad , suitable for pulsed laser ranging system time interval measurement method comparison and analysis , choose the the analog interpolation method as this topic time interval measuring system . And hardware circuit and microcontroller control system design, the amplifying circuit simulation software to verify the correctness of the system design time proportion optimized design . Time interval measurement system of the final design of the experimental apparatus . On the basis of analysis of the measurement error , given the error causes , and to propose appropriate solutions .
