Fibre optic fizeau intererometer for optical coherence tomography [PDF]

, 2006
The aim of the project was to develop the Fizeau interferometer configuration to take advantage of the benefits derived from its “downlead insensitivity” to temperature and polarisation fading.

Depth-Resolved Wavefront Aberrations using a Coherence-Gated Shack-Hartmann Wavefront Sensor [PDF]

, 2010
In the present paper we investigate the possibility of narrowing the depth range of a physical Shack - Hartmann (SH) wavefront sensor (WFS) by using coherence gating.

Double anterior chamber in a patient with glaucoma and microspherophakia

Indian Journal of Ophthalmology, 2011
We report the case of a 16-year-old woman with microspherophakia and secondary open angle glaucoma. The patient presented with a membrane dividing the anterior chamber into two segments without edema or Descemet′s membrane detachment.

Evaluation of Epithelial Downgrowth Using Anterior Segment Optical Coherence Tomography: A Case Report

, 2013
Epithelial downgrowth is a rare, sight-threatening complication which can develop following anterior segment surgeries with corneal incisions. However, due to translucent nature of epithelial membrane and diversity of clinical signs, epithelial ...

Leveraging modified ex situ tomography data for segmentation of in situ synchrotron X‐ray computed tomography

Journal of Microscopy, EarlyView.
Abstract In situ synchrotron X‐ray computed tomography enables dynamic material studies. However, automated segmentation remains challenging due to complex imaging artefacts – like ring and cupping effects – and limited training data. We present a methodology for deep learning‐based segmentation by transforming high‐quality ex situ laboratory data to ...
