Non-reflective Event Locating Based on Impulse Response in Optical Time-domain Measurement

摘要

A new construction and comparison method for accurate non-reflective event locating in optical time-domain measurement is described. We defined the backscatter impulse response, and established the convolution equations, in which the tow elements: q(t) and y(t) are measurable. With this method, we can improve the accuracy of locating of nonselective event to one sampling span, with the same the probe pulse width.
