Research Overview

Handheld Simultaneous Scanning Laser Ophthaloscopy and Optical Coherence Tomography System

SLO is a confocal imaging technique that produces real-time, high contrast 2D en-face retinal images by using raster scanning illumination and detecting backscattered light through a pinhole.

Handheld, rapidly switchable, anterior and posterior segment swept source optical tomography

Researchers have developed handheld OCT instruments. A few of these instruments are capable of imaging both the anterior and posterior segment but switching between modes requires the operator to manually remove and/or add an additional lens or lens system.

Nonfluorescent Structured Illumination

Techniques such as SIM, STED, and STORM, have found tremendous success in fluorescent imaging.

Dual Spot Swept Source Optical Coherence Tomography using Coherence Revival

Optical coherence tomography (OCT) is widely used in ophthalmology today. Despite this, patient motion is often much faster than current commercial OCT systems. When this occurs, the patient motion corrupts and distorts the image. This has driven the research community to develop methods to increase the acquisition speed of OCT.
