Query: Wavefront shaping for opaque cylindrical lenses   Wavefront shaping has revolutionized the concepts of optical imaging and
focusing. Contrary to what was believed, strong scattering in the optical paths
can be exploited in favor of light focusing through turbid media and ultimately
improve optical imaging and light manipulation capabilities. The use of light
shapers and appropriately engineered scattering structures, i.e. opaque lenses
enables the production of nano-scale confined foci and of extended fields of
view. Exploiting this concept we fabricate configurable scattering structures
by direct femtosecond laser writing. The properly shaped light trespassing the
customized structure, a photonic lattice of parallel rods, forms a light-sheet
at user defined positions. We demonstrate that our technique enables
light-sheets with sub-micron resolution and extended depth of focus, a
significant advantage when compared to the existing free space systems.
Moreover, our approach permits to focus light of different wavelengths onto the
same defined position without moving any optical element and correcting for
chromatic aberrations. Furthermore, we demonstrate how an opaque cylindrical
lens can be created using a biological structure, hence unveiling the potential
advantages for optical microscopic and mesoscopic imaging.
