北極星編碼器
編碼器（encoder）是將信號(hào)（如比特流）或數(shù)據(jù)進(jìn)行編制、轉(zhuǎn)換為可用以通訊、傳輸和存儲(chǔ)的信號(hào)形式的設(shè)備。 編碼器把角位移或直線位移轉(zhuǎn)換成電信號(hào)，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．接觸式采用電刷輸出，一電刷接觸導(dǎo)電區(qū)或絕緣區(qū)來表示代碼的狀態(tài)是"1”還是“0”；非接觸式的接受敏感元件是光敏元件或磁敏元件，采用光敏元件時(shí)以透光區(qū)和不透光區(qū)來表示代碼的狀態(tài)是"1”還是"0”，通過"1”和“0”的二進(jìn)制編碼來將采集來的物理信號(hào)轉(zhuǎn)換為機(jī)器碼可讀取的電信號(hào)用以通訊、傳輸和儲(chǔ)存。
