Off-axis multi-wavelength dispersion controlling metalens for multi-color imaging

Dispersion control is crucial in optical systems, and chromatic aberration is an important factor affecting imaging quality in imaging systems. Due to the inherent property of materials, dispersion engineering is complex and needs to trade off other aberration in traditional ways. Although metasurfa...
