Using a Fabry-Perot cavity with high transmittivity, it is possible to realize high-efficiency interaction-free measurements. In the scheme, it is required to stabilize the Fabry-Perot cavity at a resonance position when the measurements are performed. We have developed the stabilized Fabry-Perot cavity using the Pound-Drever method and demonstrated interaction-free measurements. The probability of detecting the presence of an object without any photons being absorbed was 97.4%. And the probability of detecting the absence of an object was 78.6%. Hence, the efficiency of our interaction-free measurements is 88%. Scanning an object within the Fabry-Perot cavity, we can image it without 88% of incident photons being absorbed.

利用高透过率的法布里-珀罗腔，可以实现高效率的无相互作用测量。在该方案中，当进行测量时，要求将法布里-珀罗腔稳定在共振位置。我们利用Pound-Drever方法发展了稳定的法布里-珀罗腔，并演示了无相互作用测量。探测到物体存在而没有吸收任何光子的概率为97.4%。检测到物体缺失的概率为78.6%。因此，我们的无交互测量的效率为88%。扫描法布里-珀罗腔内的物体，我们可以在没有88%的入射光子被吸收的情况下对其成像。
