摘要

提出了一种基于林尼克干涉仪的定量相位成像(QPI)中任意调整焦点位置的方法。我们的设置采用了一种独特的样品配置,其中透明物体由林尼克干涉仪成像。通过在林尼克干涉仪上引入可调焦透镜,我们成功地将时空相干门控与焦点定位解耦,在不干扰光程长度的情况下实现了动态聚焦。在不进行机械扫描的情况下,获得聚苯乙烯珠和活培养细胞的深度切片定量相图像。

Dynamic focusing in low-coherence quantitative phase imaging with decoupling of spatio-temporal coherence gating and geometric focusing
We describe an approach for arbitrarily adjusting the focal positions in quantitative phase imaging (QPI) based on a Linnik interferometer. Our setup employs a unique sample configuration in which transparent objects are imaged by a Linnik interferometer. By introducing a focus-tunable lens on top of the Linnik interferometer, we successfully decoupled the spatio-temporal coherence gating from the focal positioning and achieved dynamic focusing without disturbing the optical path length. Depth-sectioned quantitative phase images of polystyrene beads and live cultured cells were obtained without mechanical scanning.
