APD单光子探测的电路设计
Circuit Design of Single-Photon Detector Based on APD
摘要
Abstract
In the field of gas analysis due to the reduced molecular density,Raman technique is difficult to obtain a suf⁃ficiently strong signal,a single photon detector is designed based on an avalanche photodiode to improve the detection sensitivity of the weak Raman light . The system has four main modules around APD:offset/test power supply,tempera⁃ture control module,signal conditioning,pulse output. The dark count rate of the system is tested,and by using the stan⁃dard gas the accuracy of the system was calibrated. The results showed that standard deviation is up to 0.905,accord⁃ing to the total process,reproducibility relative standard deviation can be calculated to 0.905%,while the non-linear er⁃ror to take as maximum reference error is 0.13%. Its good linearity measurements can be used for linear detection.关键词
