WebDec 31, 2024 · Optical coherence tomography (OCT) is an imaging tool frequently used to take high-resolution images of the back of the eye, your retina. OCT allows your optometrist to see the specific layers of your retina through the use of light waves. Your eye doctor can map and measure the thickness of these layers. WebMar 31, 2024 · How Does OCT Work? Experts draw parallels between OCT and ultrasounds, but OCT uses light rather than sound. The non-invasive test sends light beams into the eyes, which are then bounced back to the sensors. Just like an ultrasound uses sound echoes to visualize tissues and organs in your body, OCT images tell the machine the size and …

Anterior segment OCT (ASOCT) imaging was first described in 1994 by Izatt et al [1] using the same wavelength of light as retinal OCT, namely 830nm.
WebOptical spectrometers are the most common type of spectrometer. They take light, separate it by wavelength and create a spectra which shows the relative intensity of these separate wavelengths. This basic principle has a wide range of applications and uses. Broadly speaking, all optical spectrometers consist of an entrance slit, a diffraction ...
