編碼器（encoder）是將信號（如比特流）或數據進行編制、轉換為可用以通訊、傳輸和存儲的信號形式的設備。編碼器把角位移或直線位移轉換成電信號，前者稱為碼盤，后者稱為碼尺。按照讀出方式編碼器可以分為接觸式和非接觸式兩種；
由一(yi)個(ge)中心有(you)(you)軸的(de)光(guang)電碼盤，其上有(you)(you)環形通、暗的(de)刻(ke)線，有(you)(you)光(guang)電發射和接收(shou)器件讀取，獲(huo)得四組正弦波信號組合成(cheng)A、B、C、D,每個(ge)正弦波相差(cha)90度(du)相位(wei)差(cha)（相對于(yu)一(yi)個(ge)周波為360度(du)），將(jiang)C、D信號反(fan)向(xiang)，疊(die)加在A、B兩相上，可增(zeng)強穩定(ding)信號；另每轉輸(shu)出一(yi)個(ge)Z相脈沖以(yi)代(dai)表零位(wei)參(can)考位(wei)。
