Experimental Set-up of the Microscope (IMAGE) Optica Caption How do you see through a wall of fog and still make a clear image? Researchers using a specialized version of an adaptive optics microscope have seen through an obscuring "scattering medium" to focus in on incredibly small details -- a first without using an invasive "guide star" for reference. This graphic illustrates the experimental setup in which incredibly brief laser pulses are monitored and refocused by a Spatial Light Modulator (SLM) so they can pass through the scattering medium to image otherwise hidden details on a target sample.
