OPHTHALMIC OPTICAL COHERENCE TOMOGRAPHY SYSTEM AND PROTOMERITE/DEUTOMERITE IMAGING METHOD BY QUICK SWITCHING

摘要

An ophthalmic optical coherence tomography (OCT) system and protomerite/deutomerite imaging method by using the system for quick switching, the system comprising an OCT interferometer primary module, and a sample arm module; the OCT interferometer primary module comprises an OCT light source (101), an optical fiber coupler (102), a reference arm (104), a detection module (106), an X direction scanning unit (109), and a Y direction scanning unit (110). The sample arm module comprises an eye protomerite imaging module and an eye deutomerite imaging module; the Y direction scanning unit (110) is rotatable; when the Y direction scanning unit (110) is at a first rotation angle, the light received by the X direction scanning unit (109) is reflected into the eye protomerite imaging module; and when the Y scanning unit (110) is at a second rotation angle, the light received by the X direction scanning unit (109) is reflected into the eye deutomerite imaging module. The present method achieves simultaneous imaging and quick switching at the positions of different depths, thus accurately measuring ocularaxis length.
