本文描述了一个计算成像平台,以确定各向异性光学探针的微分干涉对比(DIC)显微镜下的方向。我们基于从不同方向的金属纳米颗粒光学探针收集的DIC图像数据集建立了深度学习模型。该模型预测了金纳米棒的面内角度,误差低于20°,这是DIC方法的固有限制。使用低对称性金纳米星作为光学探针,我们展示了在0-360°范围内检测面内粒子取向。我们还表明,即使在成像背景的变化,相同粒子的取向预测是一致的。最后,深度学习模型被扩展到通过并发分析在多个波长下测量的DIC图像来同时预测多分支纳米星的面内和面外旋转角度。我们描述了一个深度学习平台,用于识别微分干涉显微镜中使用的各向异性光学探针的三维方向。
This paper describes a computational imaging platform to determine the orientation of anisotropic optical probes under differential interference contrast (DIC) microscopy. We established a deep-learning model based on data sets of DIC images collected from metal nanoparticle optical probes at different orientations. This model predicted the in-plane angle of gold nanorods with an error below 20°, the inherent limit of the DIC method. Using low-symmetry gold nanostars as optical probes, we demonstrated the detection of in-plane particle orientation in the full 0–360° range. We also showed that orientation predictions of the same particle were consistent even with variations in the imaging background. Finally, the deep-learning model was extended to enable simultaneous prediction of in-plane and out-of-plane rotation angles for a multibranched nanostar by concurrent analysis of DIC images measured at multiple wavelengths. We describe a deep-learning platform for identifying the three-dimensional orientation of anisotropic optical probes used in differential interference contrast microscopy.
