在與被測軸同心的碼盤上刻制了按一定編碼規(guī)則形成的遮光和透光的軌道。碼盤的一邊是發(fā)光LED，另一邊則是接收光線的傳感器。碼盤隨著被測軸的轉(zhuǎn)動使得透
過碼盤的光束產(chǎn)生間斷，通過光電器件的接收和電路的處理，產(chǎn)生電信號的輸出，再經(jīng)過數(shù)字處理可計算出位置和速度信息。
進行檢測，這兩個傳感器檢測出來的信號會有一定的相位偏差。從這組帶相位差
的信在光電編碼器中每個傳感器用于一路信號的檢測。一條碼道可以配合兩個傳感器號我們可以得到更多的信息比如旋轉(zhuǎn)方向。如果我們需要零位信號用于脈沖計數(shù)的校正，通常碼盤上還會有另一條軌道用于產(chǎn)生零位信號。
