摘要:

提出了一种将成像激光和超声波相结合的光子噪声和衍射极限成像方法。激光光学反馈成像(LOFI)技术是一种超灵敏的成像方法,用于通过散射介质或嵌入散射介质中对物体进行成像。然而,LOFI性能受到实验装置中发生的寄生光反馈的极大限制。在这项工作中,我们已经标记的弹道光子的声光效应,以过滤寄生反馈效应,并达到理论和最终的灵敏度的LOFI技术。介绍了声光激光光反馈成像(AO-LOFI)技术的原理和实验装置,并对寄生反馈进行了抑制。

英文摘要:

We present a photon noise and diffraction limited imaging method combining the imaging laser and ultrasonic waves. The laser optical feedback imaging (LOFI) technique is an ultrasensitive imaging method for imaging objects through or embedded within a scattering medium. However, LOFI performances are dramatically limited by parasitic optical feedback occurring in the experimental setup. In this work, we have tagged the ballistic photons by an acousto-optic effect in order to filter the parasitic feedback effect and to reach the theoretical and ultimate sensitivity of the LOFI technique. We present the principle and the experimental setup of the acousto-optic laser optical feedback imaging (AO-LOFI) technique, and we demonstrate the suppression of the parasitic feedback.
