Abstract

Holoscopy is a new imaging approach combining Digital Holography and Full-field Fourier-domain Optical Coherence Tomography. The interference pattern between the light scattered by a sample and a defined reference wave is recorded digitally. By numerical processing of the recorded interference pattern, the back-scattering field of the sample is reconstructed with a diffraction limited lateral resolution over the whole measurement depth since numerical refocusing overcomes the limitation of the focal depth. We present two setup configurations - a low resolution setup based on a Michelson interferometer and a high resolution setup based on a Mach-Zehnder interferometer. Successful measurements were demonstrated with a numerical aperture (NA) of 0.05 and 0.14, respectively and will be presented. Additionally, the effects of filtering spatial frequencies in terms of separating sample signals from artifacts caused by setup reflections is discussed and its improvement on the image quality is shown. © 2012 SPIE.
