102 fps incoherent digital motion-picture holography system for sensing of moving fluorescence nanoparticles (DTu6H.1)
Presenter: Tatsuki Tahara, National Inst of Information & Comm Tech

We present an incoherent digital holography system with 102 fps for simultaneous, holographic, and microscopic motion-picture sensing of multiple fluorescence nanoparticles. We utilize single-path single-shot phase-shifting incoherent digital holography with a birefringent material array.

Visibility enhancement method of geometric-phase self-interference incoherent digital holography with residual bias noise (DTu6H.2)
Presenter: KiHong Choi, Electronics and Telecommunications Research Institute

The visibility of the reconstructed image degraded by the residual bias noise, obtained from the geometric-phase self-interference incoherent digital holography, can be enhanced applying the bias level shifting method to the complex hologram.

Depth-resolved speckle correlation using quasi-incoherent imaging interferometry (DTu6H.3)
Presenter: Vamara Dembele, Lulea University of Technology

We described a new concept on a depth-resolved investigation based on imaging interferometry. It exploits a quasi-incoherent imaging interferometry scheme and speckle image correlation techniques. We can spatially resolve a depth-gating capacity of the imaging interferometer with a resolution of around 26 µm.

72 fps incoherent two-color digital motion-picture holography system for fluorescence cell imaging (DTu6H.5)
Presenter: Tatsuki Tahara, National Inst of Information & Comm Tech

We present an incoherent two-color digital holography system to record holograms with 2,048 x 2,048 pixels at 72 fps for fluorescence-stained cell imaging. We utilize single-shot wavelength-multiplexed incoherent digital holography with computational coherent superposition.

Underwater holographic descattering with synthetic polarization (DTu6H.6)
Presenter: Yanmin Zhu, The University of Hong Kong

We propose a novel digital holographic microscope system with synthetic polarization. It can obtain the light intensity of different polarization states in a single shot and achieve the descattering of underwater imaging through polarity calculation.

Errors in Determining Coordinates in the Digital Holography of Particles (DTu6H.7)
Presenter: Victor Dyomin, National Research Tomsk State University

Based on the approach applied to diffraction-limited optical systems, the study evaluates the measurement errors of transverse and longitudinal coordinates of particle images reconstructed from digital holograms. The paper shows the experimental results of testing the above estimates.

Crack detection in tableware items using digital holography interferometry (DTu6H.8)
Presenter: Lavlesh Prajapati, CSIR-Central Scientific Instruments Orga

Double exposure digital holographic interferometry is used for detection of cracks in tableware cup. Quantitative analysis is performed by 2-D profile and 3-D mesh plot of defects. Experimental results are validated by a mechanical profiler.
