利用可调加性噪声增强准分子laser脉冲定时控制
Enhanced control of excimer laser pulse timing using tunable additive noise
摘要：
最近，我们已经展示了一种用于精确控制准分子激光器的激光脉冲定时的系统[1]。该电子电路基于嵌入式微控制器，并利用激光脉冲产生的自然抖动噪声来改善与外部触发脉冲相关的激光延迟的长期调节。基于我们的研究结果，我们已经开发出一种改进的系统，使用额外的，可编程的时间延迟单元来调整噪声源，以进一步提高性能，并允许在同一时间内降低复杂性。混合信号微控制器生成脉冲发生时刻的随机抖动延迟，以提高分辨率，并运行专用算法以优化调节。紧凑、灵活的硬件支持进一步的增强;信号处理算法甚至可以通过系统内重新编程来替换。优化的处理和宽松的硬件要求还可以支持低功率操作、无线通信，因此应用可能性可以扩展到许多其他学科。
英文摘要：
Recently we have shown a system developed to precisely control the laser pulse timing of excimer lasers [1]. The electronic circuit based on an embedded microcontroller and utilized the natural jitter noise of the laser pulse generation to improve the long term regulation of the delay of the laser related to an external trigger pulse. Based on our results we have developed an improved system that uses additional, programmable time delay units to tune the noise source to further enhance performance and allows reduction of complexity in the same time. A mixed-signal microcontroller generates a randomly dithered delay of the pulse generation moment to enhance the resolution and also runs a dedicated algorithm to optimize regulation. The compact, flexible hardware supports further enhancements; the signal processing algorithm can be replaced even by in-system reprogramming. Optimized processing and the relaxed hardware requirements may also support low-power operation, wireless communication, therefore the application possibilities may be extended to many other disciplines.
