This technology has revolutionised optics in recent years, with many applications in imaging and
holography, adaptive optics and wavefront shaping of light
through opaque media.
The title alludes to Lewis Carroll's (Charles Lutwidge Dodgson) Alice's Adventures in Wonderland, 1865, which featured the familiar grinning Cheshire Cat; Carroll's 1871 sequel
Through the Looking - Glass and What Alice Found There; and, less familiarly, a paradoxical theory within
holography, mathematics, and quantum physics which describes variables within visibility.
