    • Disclosed is a radiation detector which includes at least one photoconductive detector (6) and a modulator (2), which modulates in an on-off manner radiation passing to the photoconductive detector (6) from a radiation source (4). A bias source (8) is connected to one terminal of the photoconductive detector (6). A first amplifier (17) is connected to the other terminal of the photoconductive detector (6), and a second amplifier (34) receives an output of the first amplifier (17). A first phase detector (36) detects the phase of modulation of the radiation source (4) by the modulator (2) and generates a reference signal relating thereto. A switch (34) in the second amplifier (24) changes, in response to the reference signal generated by the first phase detector (36), the second amplifier between an inverting state and a non-inverting state as the modulator (2) changes the phase of modulation of the radiation.
    • 公开了一种辐射检测器,其包括至少一个光电导检测器(6)和调制器(2),其调制从辐射源(4)通过光导检测器(6)的通断方式的辐射。 偏置源(8)连接到光电导检测器(6)的一个端子。 第一放大器(17)连接到光电导检测器(6)的另一个端子,第二放大器(34)接收第一放大器(17)的输出端。 第一相位检测器(36)通过调制器(2)检测辐射源(4)的调制相位并产生与之相关的参考信号。 响应于由第一相位检测器(36)产生的参考信号,第二放大器(24)中的开关(34)响应于调制器(2)改变的反相状态和非反相状态而改变第二放大器 辐射的调制阶段。
