The Goos–Hänchen effect has found many important applications in photonics and optoelectronics since its discovery 1947. Here, we propose unique of the optical differential operation image edge detection. This Letter describes theoretical foundation experimental realization proposed scheme. By incorporating with microscopy technique, our scheme may find cell molecular imaging.
Bright-field imaging and edge can extract different characteristics from objects, therefore play important roles in image processing pattern recognition. Here, we propose a fast, convenient, electrically driven adjustable scheme to achieve tunable edge-enhanced images based on computing metasurfaces. The metasurface perform spatial differential operation as optical waves propagate through it. This is polarization-dependent, thus any desirable contrast be realized by the interplay between two...
