An apparatus for parallel optical coherence tomographic funduscope includes an illumination arm, a processing unit, and a retina imaging interferometer. The illumination arm includes a light source used for emitting incident lights; the processing unit is used for processing raw images from the retina imaging interferometer to obtain fundus images; and the retina imaging interferometer which includes a sample arm, a reference arm, a detection arm and a blocking unit to block unwanted back reflections from optical elements and eye, is used for acquiring the raw images by a camera in the detection arm. The illumination and the reference arms are located in a first light path and the sample and the detection arms are located in a second light path. The blocking unit include a detection pupil located at the intersection of the first and second light paths to block unwanted back reflections from optical elements and eye.
