Figure 3. TPP fabrication of micropatterns on flat glass surface by the optimized MRAF-CGH.

(a–f) SEM images of numbers (serial, “0”, “1”, “7”), letters (“USTC”) and Olympic logo. The fabrication time of each array is within 400 ms. (g) The reading procedure of the TPP fabricated QR code “Apple”. The fluorescence image of QR code was achieved by a fluorescence microscopy and further grayed and reversed to be read by a handle reorganization device. Scale bars are 10 μm.
