我们描述了一种干涉方法，使测量两个连续的飞秒激光脉冲之间的光路延迟的色散干涉法。这种方法允许飞秒激光器被用作在广泛范围内执行绝对距离测量的源，以前所未有的精度。我们的测试结果表明，非模糊范围类似于1.46毫米，分辨率为7纳米，最大距离达到类似于0.89米。(c)2006年美国光学学会。
We describe an interferometric method that enables to measure the optical path delay between two consecutive femtosecond laser pulses by way of dispersive interferometry. This method allows a femtosecond laser to be utilized as a source of performing absolute distance measurements to unprecedented precision over extensive ranges. Our test result demonstrates a non-ambiguity range of similar to 1.46 mm with a resolution of 7 nm over a maximum distance reaching similar to 0.89 m. (c) 2006 Optical Society of America.
