Fourier-domain holography (FDH) has several advantages over image-domain holography for optical coherence imaging of tissue. Writing the hologram in the Fourier plane significantly reduces background arising from reference light scattered from the photorefractive holographic film. The ability to use FDH is enhanced by the use of a diffuse target, such as scattering tissue, rather than specular ...
