Ophthalmology oct system and ophthalmology imaging method

Abstract

The embodiment of the invention discloses an ophthalmology OCT system, comprising a posterior segment intraocular OCT imaging system and an anterior eye segment OCT imaging system. The posterior segment intraocular OCT imaging system comprises a light path conversion device, the anterior eye segment OCT imaging system comprises an anterior eye segment probe imaging device comprising an ophthalmoscope, a first dichroscope and a first lens; wherein, when the ophthalmology OCT system carries out an anterior eye segment scanning imaging, and after the light path conversion device receives a light path conversion instruction, signal light passing through a collimating mirror and a scanning device respectively are converted to the anterior eye segment probe imaging device; the anterior eye segment probe imaging device drives the first dichroscope to reflect the signal light to the ophthalmoscope to carry out the anterior eye segment scanning imaging. Correspondingly, the invention also discloses an ophthalmology OCT imaging method. By employing the invention, when the anterior eye segment imaging is carried out on human eye, fixation points can always be kept clear via refractive compensation, and the anterior eye segment probe imaging quality is not affected.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to an ophthalmic OCT system and an ophthalmic OCT imaging method. Background technique [0002] Optical coherence tomography (OCT, Optical Coherence Tomography) is an emerging optical imaging technology.
