Ultrafast electron microscopy Reinventing femtosecond atomic-scale imaging

Written by

Transmission electron microscopy may have brought about some of the most cutting-edge research into materials physics, but the technique doesn’t come without its limitations. In his research, Dr Jinfeng Yang at Osaka University in Japan aims to further improve the capabilities of the most powerful microscopes ever made, by accelerating the pulsed beams of electrons they produce to relativistic speeds. Through several […]

Novel 3D microscope provides unprecedented moving images of biological processes

This article explores the work of Dr Chunqiang Li from the University of Texas at El Paso has developed a novel 3D optical microscope that uses a spectrally shaped pulse laser.

Dr Chunqiang Li and his team of the University of Texas at El Paso have developed a novel three-dimensional (3D) optical microscope that uses a spectrally shaped pulse laser. Whilst most prior microscopes used scanning to achieve high speed 2D imaging, Dr Li’s approach obtains the z-position from a technique called ‘temporal focusing’ that use ‘diffraction’ rings and clever mathematics […]
