ABSTRACT
This article has presented a detailed design example of a simple instrument that can be used to measure speed by monitoring the time between two optical events. Although this embodiment was designed to measure times in the milliseconds-to-minutes range, the technique can easily be extended to elapsed times down into the microsecond or even nanosecond range. Operation in these domains would, however, require significant changes to the sensor and the analog signal processing circuits.
摘要：
這篇文章論述一個簡單儀器的詳細的設計實例，這臺儀器通過測定物體通過在兩束光之間的時間來測定速度。這種設計，在時間域內(nèi)可以實現(xiàn)從毫秒到分鐘（milliseconds-to-minutes）的測量， 也就是說，這種技術很容易成倍延伸到更小的時隙達到微秒“或”甚至毫微秒范圍。 當然，在這一領域進行操作的話， 重要的要求就是傳感器的設計和模擬信號處理電路的設計。
