We report a method to image facial sebaceous glands (SGs) using smartphone-enabled wide-field autofluorescence photography (AFP) and handheld swept-source optical coherence tomography (SS-OCT). Smartphone-enabled AFP provides a 2D wide-field fluorescence image that is used both as a functional mapping of the sebum and a positioning guidance for OCT imaging of the SG. Following the guidance, handheld SS-OCT conducts the volume scan to investigate depth-resolved conditions of the SG in the selected regions of interest. We show the results from smartphone-enabled AFP and handheld SS-OCT to demonstrate the ability of our method to image facial SGs, potentially useful for the assessment of skin conditions in dermatology and cosmetology.
我们报告了一种使用智能手机实现的宽场自发荧光摄影（AFP）和手持式扫频源光学相干断层扫描（SS-OCT）来成像面部皮脂腺（SG）的方法。智能手机实现的 AFP 提供了 2D 宽场荧光图像，既可以作为皮脂的功能图，也可以作为 SG 的 OCT 成像的定位指导。按照指导，手持式 SS-OCT 进行体积扫描，以研究选定感兴趣区域中 SG 的深度分辨条件。我们展示了智能手机实现的 AFP 和手持式 SS-OCT 的结果，以证明我们的方法成像面部 SG 的能力，这可能对皮肤科和美容科的皮肤状况评估有用。
