Computer-Controlled Sub-Aperture Polishing enables high-precision surface correction using small tools. Material removal is controlled by dwell time modulation along toolpaths, but the discontinuous ...

Incoming information from the retina is channeled into two pathways in the brain's visual system: one that's responsible for processing color and fine spatial detail, and another that's involved in ...

(a) Schematic of frequency multiplexing achieved by comining phase profiles derived from plate theory with wavefront-engineered phase control. (b) Photograph of the fabricated elastic metasurface that ...
