Principles Behind Optical Coherence Testing
At the heart of Optical Coherence Testing (OCT) is the revolutionary principle of low-coherence interferometry, which allows for the creation of high-resolution, cross-sectional images of internal structures. Unlike traditional imaging methods that rely on reflected light from surfaces, OCT technology penetrates materials to capture subsurface features by analyzing the echo time and intensity of returning light photons. The process begins by splitting a beam of low-coherence light into two paths: a reference path and a sample path.
The light in the sample path interacts with the target specimen, where it is partially absorbed, scattered, and reflected. The reflected light is then recombined with the reference light, creating an interference pattern that reveals detailed structural information about the internal composition of the sample. This interference phenomenon is the key to OCT’s unparalleled imaging capabilities. By precisely measuring the time delay and intensity of the returning light, OCT systems can construct detailed, micrometer-scale cross-sectional images of the specimen.
Modern OCT technologies can capture thousands of these cross-sectional scans per second, rapidly building up high-resolution, three-dimensional representations of complex structures.
