New DAbI Method Means Fast Autofocus for Microscopes (VIDEO)
Caption
A team of scientists in the lab of Changhuei Yang at Caltech has developed an inexpensive, robust method for autofocusing microscopes that involves little more than a couple of LED lights and some physics-based processing. The Digital Defocus Aberration Interference (DAbI) system has so far been tested on six different types of microscopes — from basic compound-light microscopes to more complex systems used for imaging living cells and tissues, or even thick 3D specimens — all with excellent results.
