Title:
OPTICAL COHERENCE TOMOGRAPHY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/183838
Kind Code:
A1
Abstract:
An optical coherence tomography system (100), comprising: a light source (110), an optical fiber coupler (120), a reference arm (130), a sample arm (140), a signal collection module (150) and a signal processing module (160). The light source (110) provides initial light; the optical fiber coupler (120) receives the initial light and splits the initial light into multiple paths of output light, wherein the multiple paths of output light comprise one path of reference light and one path of sample light; the reference arm (130) is used for receiving the reference light and transmitting reflected light of the reference light back to the optical fiber coupler (120); the sample arm (140) uses the sample light to detect a sample to be detected (200), wherein the sample light is scattered at the sample to be detected (200) to generate back-scattered light, the back-scattered light is transmitted back to the optical fiber coupler (120), the back-scattered light and the reflected light generate interference in the optical fiber coupler (120) to form interference light, and the interference light is split by the optical fiber coupler (120) into multiple paths of interference spectra; the signal collection module (150) is used for respectively collecting various paths of interference spectra; and the signal processing module (160) generates, according to spectral line signals of various paths of interference spectra, a detection image of the sample to be detected (200) so as to eliminate imaging interference on the sample to be detected (200).
