SSPM(固态光电倍增管)放大电路的研究与设计
摘要:在瞬态表面超高温蓝宝石光纤传感器的测试中,光电探测系统的设计是一个重要的环节,它直接影响着整个传感器的响应时间,灵敏度等因素,因此选择适合蓝宝石光纤传感器的光电探测器及其性能的测试就尤为重要。本论文首先简要介绍了高温测试系统的研究背景和意义,大体描述了目前国内外高温传感器的研究现状。其次,了解瞬态高温下蓝宝石光纤黑体腔传感器系统的工作原理后,采用非接触式辐射测温方法来研究传感器的性能。最后,在传感器光电转换模块中,应用了一种新型的固态光电倍增管(SSPM)作为光电转换元件,本论文采用SPMMicro1035×18型固态光电倍增管,并重点设计了高温测试系统中固态光电倍增管(SSPM)的适配电路。在具体电路的设计过程中,本论文创新性地提出了利用OPA657芯片来实现跨阻放大的功能。为了满足SSPM和OPA657芯片的工作要求,又分别设计了各自的电源电路部分。利用multisim软件对设计电路进行仿真,满足设计要求后,进行具体的实践性操作,设计出本论题的电路板。任何一种传感器在制造装配后都必须经过标定,建立其输入量与输出量之间的关系和确定其基本性能,如果没有精确的检测、标定手段,就无法获得传感器的静态特性和动态特性,也就不可能精确地进行量值的测量。本文设计了标定系统对传感器的静态参数进行了标定。

SSPM bits (solid-state photomultiplier tube) research and design of the amplifier circuit
Abstract: The design of the optical detection system is an important part in the testing of ultra-high temperature sapphire fiber optic sensors for transient surface, which directly affects the sensor response time, sensitivity, and therefore chosen for sapphire fiber sensor of the photodetector performance testing is particularly important. This paper first briefly introduces the research background and significance of the high temperature test system, the general description of the current domestic and foreign high-temperature sensor. Secondly, the understanding of transient high temperature sapphire fiber blackbody cavity sensor system works, the use of non-contact radiation thermometry method to study the performance of the sensor. Finally, the sensor photoelectric conversion module, the application of a new solid-state photomultiplier (SSPM), this paper SPMMicro1035 × 18 solid-state photomultiplier tube as a photoelectric conversion element, and focused on the design of solid-state photomultiplier in the high-temperature test system tube (SSPM) adapter circuit. Specific circuit design process, this paper put forward innovative OPA657 chip transimpedance amplification. In order to meet the
