Three-dimensional (3D) imaging is essential for investigating cellular structure and dynamics. Traditional optical methods ...

Cryoelectron microscopy is a method for imaging frozen-hydrated specimens at cryogenic temperatures by electron microscopy. Specimens remain in their native state without the need for dyes or ...

Electron microscopy uses a beam of electrons to illuminate a sample and achieve much higher spatial resolution than light microscopy. Transmission electron microscopy generates an image of the ...

We report on a back-illuminated single-photon avalanche diode (SPAD) based on stacked 40 nm CIS technology for short/mid-range LiDAR applications. The SPAD is optimized to achieve superior temporal ...
