An optical imaging system (1) for in-vivo retinal imaging, the system (1) comprising:an optical source (3) for generating incoherent light in a plurality of wavelength bandsan optical imaging sub-system (6) configured to split light from said optical source (3) into a plurality of beams, to introduce a path difference between said beams of light, and recombine those beams to form interference fringes that are imaged on a subject (21) andan image capture device (29) configured to capture light from the subject (21) being imaged, and to form an image of said subject (21).
