Thanks to research at the California Institute of Technology, conventional microscopes will soon be able to achieve higher resolution. Instead of replacing optics, Caltech scientists suggest using a computer program to process images.
The main hardware change to the microscope is the installation of an array of 150 LEDs instead of a conventional lamp. Turning on each light bulb in the array produces 150 different images of the same object in question. Each picture will differ slightly from each other by a slight shift in one direction. Then it's up to the computer. He will bring all the images into a single whole.
Pay attention to the stand
In the end, the resulting photograph will be 100 times more informative than than that obtained with a conventional microscope. The cost of upgrading one microscope will be about $ 200. Scientists believe the new technology could be useful in areas such as digital pathology or forensics. In addition, it can be used by hospitals in developing countries.
