低噪声光接收器
摘要：
一种低噪声光接收器，包括：光传感器(10)，用于产生传感器信号，该传感器信号包括：来自光源(9)的有用信号和来自干扰光的干扰信号；光滤波器装置(40，50)，用于减小干扰光；连接到光传感器的电滤波器装置(29，30)，用于滤出干扰信号并产生基本补偿干扰信号的校正信号；和连接到光传感器和电滤波器装置的处理装置(15，20)，用于处理有用信号以产生输出信号(Vout)。
摘要（英）：

The low noise light receiver comprises a light sensor for generating a sensor signal, the sensor signal comprising a wanted signal resulting from a light source and an interfering signal resulting from interfering light; optical filter means for reducing the interfering light; electric filter means connected to the light sensor for filtering out the interfering signal and for generating a correction signal that substantially compensates the interfering signal; and processing means connected to the light sensor and the electric filter means for processing the wanted signal in order to generatean output signal (Vout).
