用时变分析仪测量了光子对线偏振的相关性。该设备的每条腿中的分析器是一个声光开关，后面跟着两个线性偏振器。开关工作在50 MHz附近的无公度频率。每个检偏器相当于一个偏振器，它在两个方向之间跳跃的时间比光子渡越时间短。结果与量子力学预言符合得很好，但与Bell不等式相差5个标准差。
Correlations of linear polarizations of pairs of photons have been measured with time-varying analyzers. The analyzer in each leg of the apparatus is an acousto-optical switch followed by two linear polarizers. The switches operate at incommensurate frequencies near 50 MHz. Each analyzer amounts to a polarizer which jumps between two orientations in a time short compared with the photon transit time. The results are in good agreement with quantum mechanical predictions but violate Bell's inequalities by 5 standard deviations.
