Optical coherence tomography (OCT) is a high resolution biomedical imaging method

allowing for non-invasive and contace-free detecting of internal tissue structure and physiology. Ophthalmology is still the dominating field of biomedical OCT. The most important reason for that is the high transmittance of ocular media. An OCT system with broadband source (SLD) centered at 854 nm wavelength is applied for imaging in ophthalmology. Based on Fourier-domain rapid scanning optical delay line

the system is capable of imaging depth of 3mm. A device detecting the signal of eyeground is provided in this article. This device constitutes of the optical path for OCT imaging in the eyeground

the optical path for lighting of the eyeground

the optical path for obtainning photograph of the eyeground. The OCT images of macular region and optic nerve in the eyeground have been obtained.
