Non-line-of-sight (NLOS) imaging has potential in autonomous driving, robotic vision, and medical imaging but is hindered by extensive scans. In this work, we provide a time-multiplexing NLOS imaging scheme which is designed to reduce the number of scans on the relay surface. The approach introduces a time delay at the transmitting end, allowing two laser pulses with different delays to be sent per period and enabling simultaneous acquisition of data from multiple sampling points. Additionally, proof-of-concept experiments validate the feasibility of this approach, achieving reconstruction with half the scans. These results demonstrate a promising strategy for real-time NLOS imaging.
