利用光学频率梳实现不受大气参数影响的实时测距
Real-time distance measurement immune from atmospheric parameters using optical frequency combs
摘要：
我们提出了一种直接和实时的测距方案，使用光学频率梳，能够光学补偿由于大气参数的折射率变化。该方案可用于在空气中长距离要求严格精度的应用，这种情况下分散成为主要限制。关键成分是使用锁模激光器作为零差检测方案中多波长干涉测量的精确源。通过对本地振荡器进行时间整形，可以直接访问期望的参数（距离），同时对由诸如压力、温度、湿度和CO $_2$含量的环境参数引起的波动不敏感。
英文摘要：
We propose a direct and real-time ranging scheme using an optical frequency combs, able to compensate optically for index of refraction variations due to atmospheric parameters. This scheme could be useful for applications requiring stringent precision over a long distance in air, a situation where dispersion becomes the main limitation. The key ingredient is the use of a mode-locked laser as a precise source for multi-wavelength interferometry in a homodyne detection scheme. By shaping temporally the local oscillator, one can directly access the desired parameter (distance) while being insensitive to fluctuations induced by parameters of the environment such as pressure, temperature, humidity and CO$_2$ content.
