针对汽车侧滑量的测量，采用计量光栅位移传感器，根据莫尔条纹原理测量侧滑试验台滑板的机械位移，进而通过对光栅传感器的两相位置信号进行鉴相及四倍频，由单片机进行数据处理，锁定并显示测量过程中的侧滑量峰值，同时通过串行端口将侧滑量数据传送至上位PC机中。大大提高了测量速度、精度和重复性。
針對汽車側滑量的測量，採用計量光柵位移傳感器，根據莫爾條紋原理測量側滑試驗檯滑闆的機械位移，進而通過對光柵傳感器的兩相位置信號進行鑒相及四倍頻，由單片機進行數據處理，鎖定併顯示測量過程中的側滑量峰值，同時通過串行耑口將側滑量數據傳送至上位PC機中。大大提高瞭測量速度、精度和重複性。

Focus on the measurement of side slips in automobile, the article adopts the metric grating displacement transducer, according to the principle of Molte fringe, to measure the mechanical shift of sliding plate of side slip board, and by doing the phase discrimination and FHG on the dual phases signal of the grating sensor with the data processing by SCM, it locks on and shows the peak data of side slip during the measurement. Meanwhile, via serial port it transfers the side slip data to superior PC. All these can improve the testing speed, accuracy and repeatability.
