Single-pixel imaging (SPI) exploits the sparsity structure of natural images and enables image acquisition with far fewer measurements than the number of pixels. However, current SPI devices suffer from low imaging speed and an extremely time-consuming image reconstruction operation. Photonic time-stretch (PTS) technique is demonstrated to enable high-speed structured-illumination pattern generation,...
An imaging flow cytometer based on Fourier sampling is demonstrated to enable high throughput screening with a frame rate of 625 kHz and a throughput of 100,000 cells/s for the first time.
A wavelength division ultrafast microscopic imaging scheme is proposed and demonstrated. This scheme is based on wavelength-time-space mapping technique. And we use wavelength division to avoid temporal overlapping in optical fiber, the overlapped single frame is divided into two bands by optical filters. Thus each frame in different wavelength band can be received separately. By using this method,...
