论文摘要
激光可以通过使用干涉法相对较长的相干长度来识别激光器。齐赫德干涉仪结合了液晶极化调节器，证明是低成本，强大的激光检测的一种手段。时间调制，作为连贯性的特征，可以通过使用低压来调节液晶调节器的极化变化来诱导。可以实现小于10NW的敏感性。讨论了作为激光检测手段的适用性。
Lasers can be identified by their relatively long coherence lengths using interferometry. A Mach Zehnder interferometer incorporating liquid crystal polarization modulators is demonstrated as a means of low cost, robust laser detection. Temporal modulations, as a signature of coherence can be induced by modulating polarization changes in liquid crystal modulators, using low voltages. Sensitivities of less than 10nW can be achieved. The suitability as a means of laser detection is discussed.
