We present a holography-based in vivo optical phase conjugation experiment performed on a living rabbit ear. The motion of live tissues caused the phase conjugate signal to decay with a consistent decay time of less than two seconds. We monitor the signal decay time variation after the ear is excised to postulate different mechanisms that cause the signal decay. The experimental findings address the minimum speed limit of a broad range of optical time reversal experiments for in vivo applications on tissues.
我们展示了一项基于全息术的体内光学相位共轭实验,该实验在一只活兔耳朵上进行。活组织的运动导致相位共轭信号以小于两秒的一致衰减时间衰减。我们在切除耳朵后监测信号衰减时间的变化,以推测导致信号衰减的不同机制。实验结果给出了一系列用于组织体内应用的光学时间反转实验的最小速度限制。
