Lessons of conventional imaging let scientists see around corners

Along with flying and invisibility, high on the list of every child`s aspirational superpowers is the ability to see through or around walls or other visual obstacles. That capability is now a big step closer to reality as scientists from the University of Wisconsin-Madison and the Universidad de Zaragoza in Spain, drawing on the lessons of classical optics, have shown that it is possible to image complex hidden scenes using a projected `virtual camera` to see around barriers.
