一、概述本编码器是将红外激光雷达的方位轴和俯仰轴的机械转角转换成十九位二进制数码实时输送给打印机、计算机和显视设备,并以十四位串行码的形式实时输送给雷达引导设备。轴角转换元件采用电子部21所生产的一种新型的电容、电感传感器机组。由于该传感器采用了反馈补偿绕组及水银液体电刷等新技术,使系统性能大大改善。又由于线路部分采用了集成电路和许多新技术,使得本编码器系统精度高(均方根误差不大于2.5弧秒,整机分辨率和重复性均优于2.5弧秒)和稳定可
I. Overview This encoder converts the mechanical corner of the azimuth and pitch axes of an infrared laser radar into a 19-bit binary number that is delivered in real time to printers, computers, and visual devices and delivered in real time in the form of a fourteen-bit serial code Guide the radar equipment. The shaft angle conversion element uses a new type of capacitive, inductive sensor unit produced by Electronics Division 21. As the sensor uses a feedback compensation winding and mercury liquid brush and other new technologies, the system performance greatly improved. In addition, the integrated circuit and many new technologies are adopted in the line part, which makes the encoder system with high precision (root mean square error is less than 2.5 arc second, resolution and repeatability are better than 2.5 arc second) and stable
