摘要:

介绍了激光光学反馈成像(LOFI)技术在相干显微术中的应用。这种使用频移光学反馈的简单而有效的技术需要扫描样品以获得图像。讨论了检流镜扫描引起的渐晕、场曲等对幅相信号的影响。提出了一种简单的基于相位图像的监测方法,以找到扫描器的最佳位置。最后,一些实验结果说明这种技术。

英文摘要:

The application of the non conventional imaging technique LOFI (Laser Optical Feedback Imaging) to coherent microscopy is presented. This simple and efficient technique using frequency-shifted optical feedback needs the sample to be scanned in order to obtain an image. The effects on magnitude and phase signals such as vignetting and field curvature occasioned by the scanning with galvanometric mirrors are discussed. A simple monitoring method based on phase images is proposed to find the optimal position of the scanner. Finally, some experimental results illustrating this technique are presented.
