Optical coherence tomography (OCT) has become a versatile and useful tool in biomedical imaging . The technique has provided high-quality images of the eye  and other transparent tissue . OCT is based on range finding and makes use of the second-order coherence properties of a classical optical source to effectively section a reflective sample. To extend the spatial resolution in next-generation OCT, broad bandwidth sources of light are required. Such sources, however, suffer the deleterious effects of sample dispersion that limits overall imaging depth. As an alternative to the conventional light sources in OCT, we explore the merits and challenges of using nonclassical light sources for similar ranging experiments for potential application to biological imaging.
