Lensless x-ray microscope focuses on biological samples Jan 26
A "lensless" x-ray microscope that can take pictures of biological samples in their natural environment has been developed in the UK. Physicists used several overlapping diffraction patterns to create a wide field of view of samples, which they claim provides virtually instantaneous images with a resolution limited only by the x-rays' wavelength. The principle could also be implemented in a new type of large-scale 3D imaging akin to medical CT scans (Phys. Rev. Lett. 98 034801).
