Abstract
Optical coherence imaging techniques based on heterodyne detection are of increased interest for microscopic imaging and functional imaging through spectroscopic measurement and computed tomography (CT)1. While most measurements have been made by scanning the optical beam or the sample, we have recently proposed that the excellent antenna properties of optical heterodyne detection, together with its stringent requierement of the preservation of coherence and polarization of the signal light 1,2, should enable the non-scanning imaging in strongly scattering media, including tissues, by use of a two-dimensional (2D) heterodyne detector array 3. This paper presents, for the first time to our best knowledge, transillumination images of in vivo and in vitro biological objects, obtained with this new technique.
