摘　　要：简要介绍了目前比较流行的新型位置/角度传感器———钢带/钢环光栅码的工作原理;同时着重介绍了它们在2.16m望远镜的安装、使用情况,它改善了望远镜的定位精度和跟踪精度,因此有效地提高了望远镜的工作效率。At present, the tape encoder and ring encoder are a new types of the position transducers, In this paper we describe the principle of them. The paper also introduces their installation and operation on the 2.16 m telescope. They improve the precision of the pointing and tracing, thereby the telescope effeciency is enhanced effectively.
