今天,对于高精度测量,原子干涉是最先进的技术。它的应用包括:构建绝对重力仪,研究精细结构常数的变化,测量旋转角速度,以及测试等效原理等。其敏感性源于:低温下粒子的行为可以像相干波,粒子的动量决定相干波波长。为了实现和保持干涉测量所需的相干条件,大多数的装置使用复杂的激
Today, atomic interference is the most advanced technology for high-precision measurement. Its applications include: building an absolute gravimeter, studying changes in fine structure constants, measuring rotational angular velocity, and testing equivalent principles. Its sensitivity stems from: the behavior of particles at low temperatures can be like coherent waves, and the momentum of particles determines the wavelength of the coherent wave. In order to achieve and maintain the coherence conditions required for interferometry, most devices use complex excitations
