光学检流式扫描头光学检流式扫描头（Galvanometer）（以下简称扫描头）是一种有限转动的伺服电机。被特别设计用于在较大的转动角度内，实现高度线性化的转矩和偏转特性。美国通用扫描公司设计生产的光学扫描头是一种高精度、高速度的机电单元。由于具有特别适宜的转矩＼惯量
Optical Galvanometer The Galvanometer (hereinafter referred to as Scan Head) is a limited rotation servo motor. Specially designed to achieve highly linearized torque and deflection characteristics over large angles of rotation. American general scanning company design and manufacture of optical scanning head is a high-precision, high-speed electromechanical unit. Due to the particularly suitable torque / inertia
