Abstract

We review the interferometric double-imaging area (IDIA) technique,1 a new holographic principle and an optical setup for doubling the interferometric field of view of interferometric imaging setups, and obtaining wider off-axis interference areas with low-coherence light sources. The method enables measuring larger samples that cannot fit into one interferometric field of view without decreasing the microscope magnification or performing scanning, while losing in the camera frame rate. The new principle was implemented using a modified off-axis t interferometer, which is compact, portable, and easy to construct and align even with low-coherence light sources. We demonstrate using the proposed technique for imaging the quantitative phase maps of a transparent microscopic test target and live neurons.
