| Title | Design a Double-Helix Dielectric Metasurface for 3D Imaging and Depth Sensing |
| Summary | Metasurfaces, composed of subwavelength nanostructures, have revolutionized optical engineering by enabling precise control over light propagation, including amplitude, phase, and polarization. These ultrathin devices have the potential to replace bulky traditional optics while adding advanced functionalities. In this project, we aim to design and fabricate a dielectric metasurface capable of performing three-dimensional (3D) imaging and depth sensing using a single lens. The metasurface will be engineered to create a double-helix point-spread function (DH-PSF), which uniquely encodes object distances within a wide range, enabling high-resolution 3D imaging. The project will involve the design of silicon-based dielectric metasurfaces using finite-difference time-domain (FDTD) simulations to optimize the nanostructures for high transmission and precise phase control. The final goal is to experimentally demonstrate the metasurface's ability to be sensitive to the change of 3D distance, showcasing its potential applications in microscopy, robotics, and augmented reality. This project will provide students with design experience in nanophotonics, optical design, and advanced fabrication techniques. Participants will gain a deep understanding of metasurface physics. The skills acquired will be highly relevant for careers in optical engineering, photonics, and emerging technologies in consumer electronics and biomedical imaging. |
