We present phase-shifting interferometry techniques applied for multidimensional incoherent digital holography and toward ultimately low light-intensity sensing. Using incoherent holography with multiwavelength-multiplexed phaseshifting interferometry that is termed computational coherent superposition (CCS), full-color three-dimensional (3D) information of an incoherent object can be obtained from the recorded wavelength-multiplexed self-interference holograms. Furthermore, an optical setup of incoherent holography based on CCS is implemented as a palm-sized incoherent digital holographic sensing system, termed “Holosensor.” Using incoherent holography with single-shot phase-shifting holography, high-speed 3D motion-picture imaging has been demonstrated. Phase-shifting interferometry is also a powerful 3D sensing technique for ultimately low light-intensity conditions.
We present incoherent digital holographic microscopy systems for high-speed three-dimensional (3D) motion-picture sensing. Adopting single-shot phase-shifting interferometry to incoherent digital holography, high-speed motion-picture recording of spatially incoherent digital holograms can be enabled. Single-path self-interference incoherent digital holography systems are designed and constructed utilizing the polarization of light waves and birefringent optical elements. We describe the systems constructed until now and show experimental results including three-dimensional motion-picture recording of incoherent digital holograms for fluorescent nanoparticles in a flow, at the frame rate of more than 100 fps and with 1024 x 1024 pixels and the field of view of 148 um x 148 um. Furthermore, we have succeeded in extending the applicability of incoherent digital holography to 3D sensing of objects with compact optical systems. In the video presentation, single-shot quantitative phase imaging with a light-emitting diode will be introduced.
