全视场光学相干层析成像（FF-OCT）可以通过散射介质快速获取二维正面OCT图像。然而，标准的干涉仪配置浪费了近75%的光。此外，镜面反射会使探测器饱和，限制了FF-OCT的性能。在这里，我们报告了一种高通量暗场（HTDF） FF-OCT配置，它有效地利用了可用的光预算，并允许抑制镜面反射。具体来说，我们证明了与之前开发的常规FF-OCT系统相比，HTDF FF-OCT系统获得的图像具有3.5倍的信噪比。(C) 2020美国光学学会
Full-field optical coherence tomography (FF-OCT) can rapidly acquire 2D en face OCT images through a scattering medium. However, the standard interferometer configurations waste almost 75% of light. In addition, specular reflections can saturate the detector, limiting FF-OCT performance. Here, we report on a high-throughput dark-field (HTDF) FF-OCT configuration that efficiently uses the available light budget and allows suppressing specular reflections. Specifically, we demonstrate that images acquired with the HTDF FF-OCT system have 3.5 times higher signal-to-noise ratio when compared to our previously developed regular FF-OCT system.
