Abstract

Detecting fast-moving particle receives more and more attention both in physics and biology, and the study has shown its significant value either in supersonic speed or in movement of tiny biological particles. A significant amount of preparatory work has already been done to optimize this study. Always using multiple cameras or increasing the distance between detector and target, researchers can obtain favorable results. However, As the application of this technique increases, more and more challenges are emerging. One of the most obvious limitations is that confined space to lay detector. In some sense, rotating mirror can be introduced to make the system compact. It is necessary to analyze how to bring in mirror and built the system. Here, in order to use mirror capturing fast-moving target, we take a piezoelectric actuator to drive mirror, thus adopting a high angular rate to adapt to compact environment. Besides, A series of mathematical formulas and relational model are established to guide the construction of this system. Another advantage of the system, synchronous trigger signal can be triggered by laser and other means wirelessly with high precision. Therefore, having the aid of rotating mirror and wireless trigger, a fast-moving target detection system that has the virtues of no restriction of space is completed. In order to make this system in a successful operation, it is of importance to set up light path under the guidance of theoretical analysis. The experiment of trapping particles can be an effective method to show the system workflow.
