Researchers from the Optics Group have been able to obtain light intensity profiles on demand, a very precise control of light behaviour. Their research allows the increase and decrease of the depth of focus and obtaining multiple foci, with interesting technological aplications.
Current liquid crystal technology allows the production of microdisplays (LCD, Liquid Crystal Displays), with a typical size of 1 or 2 square centimetres, and with resolutions in the order of 1000x1000 pixels. These...
If there is noise, we can’t understand what we hear. In the same way, a noisy image can make it very difficult for us to recognise what we are seeing. Fortunately, techniques exist to restore noisy images so that they can be seen perfectly clearly. In this article a new restoration technique is...
