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 bands an 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) and an image capture device (29) configured to capture light from the subject (21) being imaged and to form an image of said subject (21).
