摘要
It is provided an ophthalmic optical coherence tomography system in the invention, the system comprising: an OCT interferometer primary module and a sample arm module, wherein the OCT interferometer primary module comprises an OCT light source, a fiber coupler, a reference arm, a detection module, an X-direction scanning unit, and a Y-direction scanning unit; the sample arm module comprises an anterior eye segment imaging module and a posterior eye segment imaging module; the Y-direction scanning unit is rotatable; when the Y-direction scanning unit is at a first rotation angle, the Y-direction scanning unit reflects the light received by the X-direction scanning unit into the anterior eye segment imaging module; and when the Y-direction scanning unit is at a second rotation angle, the Y-direction scanning unit reflects the light received by the X-direction scanning unit into the posterior eye segment imaging module. It is further provided a method for quick switching to realize anterior and posterior eye segments imaging in the invention, in which imaging at one time and quick switching for locations at different depths can be realized, and on this basis, the eye axial length can be measured accurately.
