We demonstrate a label-free cell analyzer with high throughput and single-cell resolution based on optofluidic time-stretch microscopy. It is capable of acquiring images of cells at a throughput beyond 10,000 cells/s with a spatial resolution of 780 nm in a label-free manner, allowing for statistical analysis of the cells' phenotypes from the images via machine learning methods. Moreover, using compressed...
We demonstrate label-free single-cell image cytometry of Euglena gracilis, a lipid-producing microalga, with a high throughput of 15,000 cells/s for evaluating and optimizing its lipid production efficiency.
We demonstrate a bidirectional Kerr-lens mode-locked dual-comb ring laser for simple and robust dual-comb spectroscopy. Two mutually coherent combs with slightly different repetition rates emitted from the single cavity enables dual-comb spectroscopy without feedback control.
We propose and demonstrate a technique for Fourier-transform CARS spectroscopy that performs broadband CARS measurements at a record high throughput of 24,000 spectra/s for diverse high-speed chemical analysis applications.
We propose and demonstrate ultrafast fluorescence confocal microscopy at a record high frame rate of 32,000 fps. This is made possible by frequency-division multiplexing with multi-line focusing.
The goal of this study is to generate droplets in a high-throughput manner without coalescence. For this purpose, an additional oil injector was applied into a conventional droplet generator. We demonstrated that our device can stabilize the droplets by injecting the additional oil. The surfactant concentration in the additional oil is higher than that in the oil for the droplet generation, resulting...
Microfluidic manipulation technology based on surface acoustic waves (SAWs) has great potential for improving biomedical and clinical practices including drug screening, sorting, and isolation of rare cells on a single-cell level via an induced acoustic force with high biocompatibility. However, previous works on the manipulation of particles/cells using acoustic methods primarily base on their intrinsic...
We present a method for motion-picture femtophotography that performs continuous, single-shot, burst image acquisition without the need for repetitive measurements. We capture the dynamics of laser ablation and phonon propagation with the imaging method.
We present a method for ultrafast automated single-cell optical microscopy that performs blur-free image acquisition and non-stop real-time image-recording and classification of cells during high-speed flow. This method is based on a unique integration of ultrafast optical imaging, self-focusing microfluidics, optoelectronics, and information technology. To show the system's utility, we demonstrate...

We report a new method of high-contrast imaging of unstained and transparent objects at ∼1000 times higher frame rates than conventional methods. As a proof-of-concept, we demonstrate enhanced image-contrast in 2D imaging of a transmission grating.
Serial time-encoded amplified microscopy (STEAM) is a new high-sensitivity ultrafast real-time imaging modality. Here we describe an analysis of its spatial resolution, frame rate, and detection sensitivity.
We report the first experimental demonstration of Raman amplification in a fiber at wavelengths near 800 nm and propose its application to fast real-time optical sensing and imaging in this technologically important band.
