We present a forward-looking, fiber-scanning endomicroscope designed for optical coherence tomography (OCT) and OCT-Angiography (OCT-A) imaging through the working channel of commercial gastrointestinal endoscopes and cystoscopes. 3.4 mm in outer diameter and 11.9 mm in length, the probe is capable of high-resolution volumetric imaging with a field-of-view of up to 2.6 mm and an imaging depth of up to 1.5 mm at a lateral resolution of 19 m. A high-precision lens mount fabricated in fused silica using selective laser-induced etching (SLE) allows the tailoring of the optical performance for different imaging requirements. A glass structure fabricated by the same method encapsulates the optical and mechanical components, providing ease of assembly and alignment accuracy. The concept can be adapted to high resolution OCT/-A imaging of various organs, particularly in the gastrointestinal tract and bladder.

我们通过商用胃肠内窥镜和膀胱镜的工作通道，提出了一种前瞻性的光纤扫描内镜，专为光学相干断层扫描 (OCT) 和 OCT-血管造影 (OCT-A) 成像而设计。该探头外径为 3.4 mm，长度为 11.9 mm，能够以高达 2.6 mm 的视场和高达 1.5 mm 的成像深度在 19 m 的横向分辨率下进行高分辨率体积成像。使用选择性激光诱导蚀刻 (SLE) 在熔融石英中制造的高精度镜头座允许根据不同的成像要求定制光学性能。用相同方法制造的玻璃结构封装了光学和机械部件，便于组装和对准精度。该概念可适用于各种器官的高分辨率 OCT/-A 成像，
