title = "Design of multi-object-distance imaging system using hybrid Moir{\'e} metalenses and refractive lenses",
abstract = "Imaging systems working for multi-object-distance are widely used. However, due to the axial moving mechanism of optical elements, the whole system may be bulky and costly. To compress volume and weight of the system, Moir{\'e} metalenses that can realize imaging for multiple object distances by relative angular rotation shifting are expected to be employed. In this paper, we propose the optical design of a multi-object-distance imager enabled by hybrid polarization-insensitive Moir{\'e}metalenses and spherical lenses. The mechanical axial movement of the optical element used in traditional zoom system is instead by rotating Moir{\'e}metalens, and whole system is thus compact and simple.",
