LIKA線(xian)性編碼(ma)器不同于LIKA旋(xuan)轉(zhuan)(zhuan)編碼(ma)器，LIKA旋(xuan)轉(zhuan)(zhuan)編碼(ma)器是旋(xuan)轉(zhuan)(zhuan)式(shi)的，常用于轉(zhuan)(zhuan)速(su)測量或(huo)是定(ding)位，而LIKA線(xian)性編碼(ma)器是走直(zhi)線(xian)，又叫光柵尺，常用在長(chang)度測量或(huo)直(zhi)線(xian)定(ding)位。

LIKA線(xian)(xian)(xian)性(xing)(xing)編(bian)(bian)碼器(qi)是(shi)(shi)一(yi)(yi)種(zhong)能(neng)夠(gou)沿直線(xian)(xian)(xian)測量(liang)位置(zhi)的(de)(de)電子傳(chuan)感(gan)(gan)(gan)器(qi)，通(tong)常用于(yu)機器(qi)人和自動(dong)化(hua)系(xi)統(tong)。有幾種(zhong)不同(tong)類型的(de)(de)線(xian)(xian)(xian)性(xing)(xing)編(bian)(bian)碼器(qi)，每種(zhong)儀器(qi)都使(shi)用不同(tong)的(de)(de)檢測方法來(lai)確定LIKA編(bian)(bian)碼器(qi)的(de)(de)位置(zhi)。能(neng)夠(gou)沿直線(xian)(xian)(xian)測量(liang)位置(zhi)的(de)(de)傳(chuan)感(gan)(gan)(gan)器(qi)被稱為LIKA線(xian)(xian)(xian)性(xing)(xing)編(bian)(bian)碼器(qi)。這(zhe)種(zhong)儀器(qi)的(de)(de)所有品(pin)種(zhong)都需要(yao)一(yi)(yi)個刻(ke)度(du)和一(yi)(yi)個傳(chuan)感(gan)(gan)(gan)器(qi)才能(neng)正確使(shi)用。刻(ke)度(du)是(shi)(shi)一(yi)(yi)塊標記(ji)有一(yi)(yi)致的(de)(de)間隔，類似于(yu)普通(tong)的(de)(de)標尺(chi)。LIKA線(xian)(xian)(xian)性(xing)(xing)編(bian)(bian)碼器(qi)裝置(zhi)內的(de)(de)傳(chuan)感(gan)(gan)(gan)器(qi)能(neng)夠(gou)在其(qi)經過滑(hua)塊時檢測到(dao)每個間隔。 每次傳(chuan)感(gan)(gan)(gan)器(qi)檢測到(dao)間隔標記(ji)并計數時，LIKA線(xian)(xian)(xian)性(xing)(xing)編(bian)(bian)碼器(qi)的(de)(de)輸出都會發生變化(hua)。LIKA線(xian)(xian)(xian)性(xing)(xing)編(bian)(bian)碼器(qi)數據(ju)有時會用于(yu)讀(du)數或顯示的(de)(de)信息目(mu)的(de)(de)。數據(ju)也可作為更復(fu)雜的(de)(de)計算機控制系(xi)統(tong)的(de)(de)一(yi)(yi)部(bu)(bu)分使(shi)用，對運動(dong)部(bu)(bu)件的(de)(de)位置(zhi)和移動(dong) 距離有反饋。
