四象限元件在脉冲激光跟踪系统和跟踪辐射能的窄脉冲系统中已经取得了广泛的应用。本文介绍四象限元件用于接收高频调制光源的信号,省掉以前在制导中所用的复杂基准信号,实现了数字化误差检测。
Four-quadrant elements have found wide applications in pulsed laser tracking systems and narrow-pulse systems that track radiant energy. This article describes four quadrant components used to receive high-frequency modulated light source signal, eliminating the previously used in the guidance of complex reference signal, digital error detection.
