摘　　要：针对海面溢油油膜厚度的测量，基于垂直入射式差分激光三角法原理，研制了可机载投放的浮标式油膜厚度测量传感器。介绍了传感器的组成和原理，给出了系统集成与调试过程，以0级陶瓷量块为标准厚度，采用最小二乘拟合高次曲线的方法对传感器进行了标定。选用1．4～9．4mm量块对传感器进行了精度测量，测量相对误差小于1％。According to the measurement of oil film thickness on the sea, an oil film thickness sensor based on buoy is developed using vertical incidence differential laser trigonometry. The composition and principle of sensor is introduced and the process of the system integration and debugging is presented. Ceramic grade 0 gauge block is measured as a standard thickness and high order curve is fitted based on least square method for the calibration of the sensor. 1.4-9.4 mm gauge blocks are measured to verify the precision. The results show that the measurement relative error is less than 1%.
