Optical coherence tomography

Optical Coherence Tomography (OCT) is a non-invasive imaging technique that provides high-resolution cross-sectional images of biological tissues, particularly in the field of ophthalmology. It utilizes light waves to capture micrometer-resolution, three-dimensional images from within tissue. Here are some key points about OCT: 1. **Principle**: OCT works by measuring the echo time delay and intensity of backscattered light from tissues.
