实验研究了具有延时反馈环的光学双折射系统中随机共振（SR）和相干共振（CR）的相互作用。我们证明了噪声引起的运动的相位被锁定的周期性输入时，它们的频率之比是一个简单的有理数。我们还表明，SR和CR之间的相互作用产生的频率混合模式，和频率混合的效率提高了最佳的噪声。
The interplay between stochastic resonance (SR) and coherence resonance (CR) is experimentally studied in an optical bistable system with a time-delayed feedback loop. We demonstrate that the phase of the noise-induced motion is locked to that of the periodic input when the ratio of their frequencies is a simple rational number. We also demonstrate that the interplay between SR and CR generates frequency-mixed modes, and that the efficiency of frequency mixing is enhanced by the optimum noise.
