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(gè)簡(jiǎn)單儀器的詳細(xì)的設(shè)計(jì)實(shí)例，這臺(tái)儀器通過(guò)測(cè)定物體通過(guò)在兩束光之間的時(shí)間來(lái)測(cè)定速度。這種設(shè)計(jì)，在時(shí)間域內(nèi)可以實(shí)現(xiàn)從毫秒到分鐘（milliseconds-to-minutes）的測(cè)量， 也就是說(shuō)，這種技術(shù)很容易成倍延伸到更小的時(shí)隙達(dá)到微秒“或”甚至毫微秒范圍。 當(dāng)然，在這一領(lǐng)域進(jìn)行操作的話， 重要的要求就是傳感器的設(shè)計(jì)和模擬信號(hào)處理電路的設(shè)計(jì)。
