New Ways of Visualizing Tear Film Using Silicon Quantum Dots (ITh1B.1)
Presenter: Maitreyee Roy, The University Of New South Wales

We developed an optical imaging system using silicon quantum dots as biomarkers to study the tear film dynamic, leading to improving ophthalmic imaging modality for dry eye treatments and effective drug delivery mechanisms.

Speeding up Four-wave-mixing Imaging Microscopy (ITh1B.2)
Presenter: Eric Martin, MONSTR Sense Technologies

Laser-scanned imaging based on spectroscopy techniques, such as four-wave-mixing imaging microscopy, are notoriously slow. Here we present techniques to improvethe rate of acquiring a laser-scanned image while preserving a high signal-to-noise ratio.

Fast refractive index tomography of living cells in conventional microscope (ITh1B.3)
Presenter: Tatiana Alieva, Universidad Complutense de Madrid

We demonstrate the application of refractive index tomography technique compatible with conventional transmission microscope for fast (10 fps) 3D living cell monitoring. The reconstructed refractive index distribution allows studying dynamics of eukaryotic cell organelle in 3D.

Lock-In Amplified Differential Phase Contrast (ITh1B.4)
Presenter: Chiara Bonati, Ecole Polytechnique Federale de Lausanne

A method for lock-in amplified differential phase contrast is described, which gives background-free, high contrast-to-noise ratio phase images. We show the advantages of this approach, and demonstrate its performance compared to standard DPC.

Spatial frequency domain imaging with a bucket detector (ITh1B.5)
Presenter: Armin Lenz, Universitat Jaume I

We present a spatial frequency domain imaging (SFDI) system based on single-pixel imaging (SPI) techniques with a single digital micromirror device (DMD) modulating simultaneously the sinusoidal pattern and the spatial sampling masks.

Tomography and Radiographic Imaging using Accelerated Muon Beam (ITh1B.7)
Presenter: Masashi Otani, High Energy Accelerator Research Organiz

Muons have been utilized to see through large structures such as the pyramids. The accelerated muons can have high intensity and monochromatic energy, allowing for better resolution imaging in less time.
