Sebum is an important component of the skin that has attracted attention in many fields,
including dermatology and cosmetics. Pore expansion due to sebum on the skin can lead to …

Compared with optical coherence tomography (OCT) in the near-infrared domain, the visible-
light OCT (vis-OCT) system affords a higher axial resolution for discerning subtle …

The trade-off between lateral resolution and depth of focus (DOF) severely limits the
capability of endoscopic optical coherence tomography (OCT) for high-resolution deep …

We present a high-resolution optical coherence tomography (OCT) imaging system that
utilizes a multi-level diffractive lens (MDL) to enhance lateral resolution. The system utilizes …

Detecting early‐stage epithelial cancers and their precursor lesions are challenging as
lesions could be subtle and focally or heterogeneously distributed over large mucosal areas …

Background There is an urgent need to develop a non-invasive imaging technique for
detecting colorectal dysplasia and cancer. Technology for early and real-time microscopic …

Endoscopic optical coherence tomography (OCT) is widely used in the detection of
morphological alterations in luminal organs, which provides high-resolution, three …

Imaging sebaceous glands and evaluating morphometric parameters are important for
diagnosis and treatment of serum problems. In this article, we investigate the feasibility of …

METHODS: Fresh tissue samples were obtained from patients with colorectal polyps or
colorectal cancer who received endoscopic therapy or laparoscopic surgery. These samples …

We report a dual-focus fiber-optic probe designed to extend depth of focus (DOF) in high-
resolution endoscopic optical coherence tomography. We exploited the broad spectral …
