Application of TDC-GP2 in Laser Range Sensor

摘要

Laser range finder sensor can get the distance between sensor and detecting target by measuring flight time of laser pulse. The designed laser pulse measurement sensor use FPGA EP2C20F as the control core of system. In order to improve measurement precision of laser flight time interval, we have designed a time interval measurement module by using a special high precision time to digital converter TDC-GP2. The testing resolution is up to 65ps. This sensor is low power dissipation and high measuring accuracy.
