1. A system for acquiring images from within depth layers of a tissue, said system comprising: an illumination source for illuminating a tissue, wherein said illumination source illuminates a large illumination beam area; a collimator for collimating the light from the illumination source; an interferometer comprising: a beam splitter located between the illumination source and the tissue; a moveable reference mirror; and an imager, wherein optical axes of said moveable mirror and said imager are perpendicular to the optical axis of collimated light from said illumination source and to collimated light from said tissue, and wherein said beam splitter is located between said moveable mirror and said imager; and a first telecentric optical system for passing through only collimated reflected light, said first telecentric optical system located between the beam splitter and the tissue; a second telecentric optical system configured to decrease intensity of light reflected off the reference mirror synchronously with movement of the reference mirror, said second telecentric optical system located between the beam splitter and the reference mirror, wherein said second telecentric optical system comprises a collimating lens, a shutter and a condensing lens, wherein said imager is configured to generate an interference pattern for each depth layer of the tissue, according to the collimated reflected light.
