摘要: 随着科学技术的快速发展，高速光学成像与超快诊断技术在科学、工业、国防和医学等领域中的应用愈发重要。同步扫描条纹相机作为一种超快光现象探测仪器，与高重频激光器协同使用，实现高精度时间同步的泵浦探测，通过对微弱光信号的累积与放大实现高信噪比探测。然而，现有同步扫描电路在长时间工作模式下，信号源器件累计高频噪声随之增加，同时存在缺少具体的阻抗匹配设计方法的问题，影响了条纹相机的时间分辨性能提升。综合考虑多种变压器结构和设计方案，基于螺旋谐振器进行谐振匹配设计，利用有限元仿真开展相关模拟研究，通过谐振器初级线圈参数的调节，实现了射频功率放大器输出阻抗和容性负载之间匹配。对设计模型进行谐振耦合升压研究表明，在一定功率输入下能够输出高峰值电压，验证了螺旋谐振方法的有效性，通过噪声响应和时间抖动对比分析表明，设计方法能够进一步提升同步扫描时间分辨性能。Abstract: With the rapid development of science and technology, the application of high-speed optical imaging and ultrafast diagnostic technologies in fields such as science, industry, national defense and medicine is becoming increasingly important. The synchroscan streak camera, as an ultrafast optical phenomenon detection instrument, is used in conjunction with high-repetition-frequency lasers to achieve high-precision time-synchronized pump detection. It realizes high signal-to-noise ratio detection by accumulating and amplifying weak optical signals. However, in the long-term working mode of the existing synchronous scanning circuit, the cumulative high-frequency noise of the signal source device increases accordingly. At the same time, there is a problem of lacking a specific impedance matching design method, which affects the improvement of the time resolution performance of the streak camera. This paper comprehensively considers various transformer structures and design schemes, conducts resonant matching design based on helical resonators, and carries out relevant simulation studies using finite element simulation. Through the adjustment of the parameters of the primary coil of the resonator, the matching between the output impedance of the RF power amplifier and the capacitive load is achieved. The research on resonant coupling boost of the design model shows that it can output peak voltage under a certain power input, verifying the effectiveness of the helical resonance method. Through the comparative analysis of noise response and time jitter, it is indicated that the design method in this paper can further improve the time resolution performance of synchronous scanning.
