摘　　要：量子光学相干层析技术(QOCT)具有高分辨率、非接触、无损检测、不受偶数阶色散影响等优点,在生物医学、材料学、精密测量等领域具有重要的应用前景。对近年来QOCT的研究进展进行了整理和归纳,主要包含3个方面:在提高分辨率方面,通过增加光源的频谱宽度来减小其时域宽度,从而使分辨率不断地获得提高;在提高成像速率方面,通过采用频域测量的方法来代替时域繁琐的扫描测量方式,大幅减少了数据采集所需时间;在伪影去除方面,通过使用新型数学算法或机器学习算法,可以显著抑制QOCT对简单样品成像过程中存在的伪影。对比分析了经典光学相干层析技术、QOCT以及量子模仿光学相干层析技术中不同方案的优缺点。结合QOCT研究的发展趋势,对今后实现更高分辨率的成像、测量更复杂的样品、高效去除伪影、开发样机等重点研究方向进行了展望,可为后续QOCT的进一步深入研究提供指导。Quantum optical coherence tomography(QOCT)has the advantages of high resolution,noncontact operation,non-destructive testing,and immunity to even-order dispersion.It has prospects for broad applications in biomedicine,materials science,precision measurement,and other fields.This article summarizes the recent research progress in QOCT,which mainly includes three aspects:in terms of improving resolution,the time-domain width of the light source is reduced by increasing its spectral width,thereby continuously improving resolution;in terms of improving imaging speed,the use of frequencydomain measurement methods instead of the cumbersome time-domain scanning measurement methods significantly reduces the time required for data acquisition;in terms of artifact removal,the use of new mathematical algorithms or machine learning algorithms can significantly suppress the artifacts in the QOCT imaging of simple samples.The advantages and disadvantages of different schemes in classical optical coherence tomography(OCT),QOCT,and quantum mimetic OCT are compared and analyzed.Based on the development trend of QOCT research,this article provides prospects for key research directions such as achieving higher-resolution imaging,measuring more complex samples,efficiently removing artifacts,and developing prototypes in the future.This can provide guidance for further in-depth research on QOCT in the future.
