| Abstract：A kind of sensor which based on the laser trigonometry principle is designed. This sensor is composed by the CCD pickup camera and the laser, it is mainly used in surveying the road surface smoothness.The
experimental result of the prototype sensor shows that this sensor may achieve 1100mm in the vertical direction survey scope, the crosswise survey scope reaches 1300mm. The crosswise mean absolute error is 0.05mm
approximately; The longitudinal mean absolute error is 0.08mm approximately. This kind of sensor hast hesurvey scope in a big way, higher precision, also can work in harsh environment condition.
