Microscopes are a dime bag a dozen in university , so there ’s batch of fun to be had hack on ’em any direction you’re able to — like a team of researchers from Caltech , whohave develop a cheap and easy wayto increase their resolution by a factor of 100 .
Normally , increasing magnification exponent of a microscope requires new internal lenses , which entail you either plump for in high spirits resolution or orotund field of survey — but not both . But a newfangled technique , developed by Changhuei Yang at Caltech andpublished in Nature Photonics , switch that .
It takes multiple low - res images of a sample distribution , each corresponding to a single light in a matrix of LEDs below . Each image is captured with a unlike light-emitting diode in the matrix light up . Then , a computer uses the low - res images in conjunction with knowledge of which LED was light up to stitch the images together into a composite plant — with resolution of up to a billion pixel . Yang excuse :
“ The optical performance of the objective lens is rendered almost irrelevant as we can improve the resolution and correct for optical aberration computationally . You only need to total an LED array to an existing microscope . No other hardware modification is involve . The rest of the job is done by the computer . ”
All in , the plug uses $ 200 of package and hardware — which in scientific research terms is filthy cheap . have a bun in the oven to try researcher everywhere giggling excitedly about their lives becoming much , much easier . [ Nature PhotonicsviaCaltechviaEngadget ]
