Scientists have found a new method to get images through scattering materials such as ice-covered glass or even skin, or still see around corners. A lot of investigate in recent years has focused on correcting for dispersion, mostly for medical applications. In 2010, a camera that can see around corners garnered much awareness, using a series of timed laser pulses to light up a scene and functioning what is around a corner from the timing of the reflections.
SLMs modify what is recognized as the phase of an incoming light ray. Like a sequence of waves on the ocean that run over rocks or surfers, the waves in beam can be slowed down or redirected when they hit dispersion materials. The prototype device was just one of a huge many study efforts trying to break the difficulty of scattering. The panel then realized that the similar approach can work in reflection, not passing through a scattering material but bouncing off of it, such as the case of light bouncing off a wall at a corner.
