Modulation and Control Technology for Generating Movable Super-Diffraction Optical Needle by Oblique Incidence

Modulation and Control Technology for Generating Movable Super-Diffraction Optical Needle by Oblique Incidence

The movable super-diffraction optical needle (MSON) is a tightly focused beam like a “needle”, which can realize vector scanning on the focusing plane. Not only does it have a long focal depth, but its resolution also exceeds the diffraction limit. The modulation and control technology required for...
