摘　　要：根据拉曼散射光的特点,选用一种由硅雪崩光电二极管(APD)组成的多像素倍增器件作为光电转换器,设计了一套单光子探测器。为降低探测过程的噪声,探测器部分设计有低纹波偏压、恒温控制和快速雪崩抑制模块.并配有用于雪崩特性研究的测试模块,并通过调整电路参数优化探测性能。测试结果表明:探测器具有响应灵敏度高、分析速度快、体积小巧、功耗低等特点,适合在气体拉曼分析系统中使用。According to the characteristics of Raman scattering light, a silicon avalanche photodiode is used to compose of muhi-pixel doubling device as a photoelectric converter. To reduce noise during detecting,the detector has modules of reverse bias supply with low ripple voltage, temperature control and fast avalanche suppression module. Moreover,it owns a test module which is exclusively for the study of avalanche phenomenon, and the perfor- mance is optimized by adjusting circuit parameters. The results indicate that the detector has high detection sensi- tivity, rapid analysis speed, small size and low power consumption, suitable for using in Raman gas analysis system.
