WebNoninvasive corneal imaging is essential for the diagnosis and treatment control of various diseases affecting the anterior segment of the eye. This study presents an ultrahigh … WebOptical coherence tomography, or OCT, is an imaging method used to generate a picture of the back of your eye, called your retina. The noninvasive method produces an image by measuring the amount of a dim red light that reflects off of your retina and optic nerve. Optical coherence tomography can measure the thickness of your retina and optic ...

We present 3D optical coherence refraction tomography (OCRT), which incoherently synthesizes an extended 3D transfer function using multi-view OCT volumes spanning two angular dimensions. Our setup features a novel use of parabolic mirrors, achieving millimetric fields of view over ± 75 without rotation stages.
