Bidirectional quantitative scattering microscopy
Kohki Horie, Keiichiro Toda, Takuma Nakamura +1
Quantitative phase microscopy (QPM) and interferometric scattering (iSCAT) microscopy are powerful label-free imaging techniques and are widely used for biomedical applications. Ea…
Ludwig-Soret microscopy with vibrational photothermal effect
Keiichiro Toda, Takuro Ideguchi
Vibrational microscopy provides label-free, bond-selective chemical contrast by detecting molecular vibrations, making it invaluable for biomedical research. While conventional met…
Phase retrieval via Zernike phase contrast microscopy with an untrained neural network
Zinan Zhou, Keiichiro Toda, Rikimaru Kurata +3
Zernike's phase contrast microscopy (PCM) is among the most widely used techniques for observing phase objects, but it lacks quantitative nature, as it cannot directly provide phas…
Fiber-based mid-infrared frequency-swept laser at 50 MScans/s via frequency down-conversion of time-stretched pulses
Makoto Shoshin, Takahiro Kageyama, Takuma Nakamura +2
Increasing the sweep rate of mid-infrared (MIR) frequency-swept sources offers significant potential for various high-speed spectroscopy-based applications. While continuous-wave f…
