用雪崩振荡器测量拉伸导线的长度
Measuring the length of stretched wires with a avalanche oscillator
摘要：
我们测量的长度拉伸线对使用它们作为延迟线脉冲整形元件在雪崩振荡器。该电路和方法非常简单，对振荡器电源电压、所用的特定晶体管（2N3904）和导线张力不敏感。模拟断线的初步测试表明，这些可以很容易地检测到。这项技术是否能在真实的线平面上大规模工作还有待观察，但它至少应该和反射短脉冲一样好。
英文摘要：
We measure the length of stretched wire pairs by using them as the delay line pulse shaping element in an avalanche oscillator. The circuitry and method are extremely simple, and insensitive to oscillator supply voltage, to the particular transistor (2N3904) used and to wire tension. Rudimentary tests with simulated broken wires show that these can be detected easily. It remains to be seen whether the technique will work at scale with realistic wire planes, but it should be at least as good as reflecting short pulses.
