摘要：
An optical coherence tomography system (100), comprising a light source (110), an optical fiber coupler (120), a lens group (130), a signal acquisition device (160), and a signal processing device (170). The light source (110) is used for emitting initial light； the optical fiber coupler (120) is used for performing beam splitting on the initial light to obtain reference light and sample light； the lens group (130) is provided on an optical path between the optical fiber coupler (120) and a sample to be tested (200)； the sample light is transmitted to the lens group (130) by means of an optical fiber, then incident to the sample to be tested (200) by means of the lens group (130), and reflected by the sample to be tested (200), thereby obtaining sample reflected light； the sample reflected light passes through the lens group (130) and undergoes interference with the reference light, thereby obtaining interfered light； the lens group (130) is used for lowering the loss of the sample light； the signal acquisition device (160) is used for detecting the interfered light to obtain an interference spectrum； the signal processing device (170) is used for processing the interference spectrum to obtain a structure image of the sample to be tested (200). The optical coherence tomography system (100) can enhance the signal of the interfered light to cause large light intensity in the interference spectrum, so that the obtained structure image of the sample to be tested (200) has a good effect.La présente invention concerne un système de tomographie par cohérence optique (100), comprenant une source de lumière (110), un coupleur de fibre optique (120), un groupe lentille (130), un dispositif d'acquisition de signal (160), et un dispositif de traitement de signal (170). La source de lumière (110) est utilisée pour émettre la lumière initiale ； le coupleur de fibre optique (120) est utilisé pour effectuer la division de faisceau sur la lumière initiale pour obtenir la lumière de
