In this Letter, we present a binocular chiral metalens (BCM) device designed for four-dimensional (4D) imaging, which integrates both three-dimensional spatial perception and polarization detection. The BCM consists of two identical monocular metalenses that spatially separate left- right-handed circularly polarized (LCP RCP) light. When integrated with commercial camera, the enable simultaneous measurement depth information. Numerical simulations experimental results demonstrate can achieve circular extinction ratio (CPER) 29.2 dB an average 3D reconstruction error 4.09%. proposed system paves pathway multi-dimensional significant potential in applications security, surveillance, future advancements more complex imaging tasks across other electromagnetic bands, including terahertz infrared regimes.
