Diffractive and micro-optics for wavefront manipulation
SPIE Proceedings, 2012The exploitation of micro-optical technologies in laser beam shaping and wavefront manipulation applications has a long and distinguished history. The functional flexibility of high resolution, allglass phase only microstructures, combined with their relative immunity to laser-induced damage mechanisms, allows the creation of arbitrary beam profiles

Dynamic PB metasurface for transmissive and reflective wavefront manipulation
Physica ScriptaBased on the phase transition characteristics of vanadium dioxide (changes in conductivity with temperature), we designed a dynamic metasurface for wavefront manipulation that can switch between transmission and reflection modes at the same frequency ...

Binary wavefront manipulation using an epi-detected SHG guidestar
BiOSMultiphoton microscopy applied in bone tissue is susceptible to optical aberrations caused by heterogeneity in refractive index. Optical clearing can be applied to alleviate some of these aberrations, but it is invasive and causes deviations from normal ...
