Lens free microscopy
Lens free microscopy Microscopy whether electron microscopy or with visible light requires lenses. For electron microscopy, lenses incur significant design challenges and add aberrations. A startup in UK uses technology invented by Professor John Rodenberg to remove lenses altogether and compute the image from the diffraction pattern of the sample. This is similar to a…

Bluesky: Diffraction images from flow cytometer
Flow cytometry typically flows particles or cells through a laminar flow cell into an interrogating laser beam to be read out as flourescent signal with a photomultiplier or photodiode. The read out is typically the integrated intensity or a two dimensional projection of a cell. The residence time is in order of 10 micro-seconds. Cellular…
