Abstract
- Liquid crystal superstructures or metasurfaces based on Pancharatnam−Berry (PB) phase have made remarkable progress in all‐optical image processing due to the advantages of miniaturization, integration, and multi‐dimensional light field modulation. However, conventional static PB phase devices are usually not tunable and with a single function. Here, based on the tunability of the moiré effect, the wavelength‐independent effect of the PB phase, and the principle of retardation compensation, an ultra‐broadband multifunction moiré‐PB doublet lens is designed, which can realize optical edge imaging with a tunable resolution ranging from 13.2 to 57.2 µm and ultra‐broadband conventional and polarimetric imaging to meet the requirement of multiple functionalities and system integration. In addition, edge feature extraction or edge imaging of low‐contrast biological samples is also realized. Benefiting from the characteristics of miniaturization, switchable multiple imaging functions, and real‐time parallel processing, this method may expand the practicability of modern optical image processing, microscopic imaging, and biomedicine.
