5m range, 75° x 54° FoV 3D Time-of-Flight Camera with Metasurface Beam Steering

3D Time-of-Flight camera with meta beam steerer

Description

MMAE068-940 is a 3D time-of-flight camera developed by Alpha Cen, based on MBS (Meta Beam Steerer) metasurface beam control. The product can control the beam of the light source through software without mechanical movement, enabling fixed-angle control and continuous or non-continuous beam scanning within the total FOV range. This product is based on the cwToF principle, with corresponding optical and electrical designs to achieve variable viewing angles for high-precision distance measurements. It supports Ethernet (100BASE-T) data communication and can output depth maps and infrared grayscale images.
