Dot-matrix surface micrograting arrays






Top:  (left) Original gray scale image. (right) Each gray scale value is mapped to a grating amplitude via exposure time. Bottom: (right) Resulting dot matrix array of surface gratings written on supramolecular film.  (middle) Magnified optical microscope image showing dot matrix structure. (left) AFM image of individual grating dot.   (More images here)
