B-spline freeform surface tailoring for prescribed irradiance based on differentiable ray-tracing
Haoqiang Wang, Zihan Zang, Yunpeng Xu +3
A universal and flexible design method for freeform surface that can modulate the distribution of an zero-étendue source to an arbitrary irradiance distribution is a significant ch…
DAD vision: opto-electronic co-designed computer vision with division adjoint method
Zihan Zang, Haoqiang Wang, Yunpeng Xu
The miniaturization and mobility of computer vision systems are limited by the heavy computational burden and the size of optical lenses. Here, we propose to use a ultra-thin diffr…
Planar multi-aperture fish-eye lens using metagrating
Zihan Zang, Haoqiang Wang, Yanjun Han +3
The design of compact optical systems with large field of view has been difficult due to the requirement of many elements or a curved focal plane to reduce off-axis aberration. We…
Ultrafast Parallel LiDAR with Time-encoding and Spectral Scanning: Breaking the Time-of-flight Limit
Zihan Zang, Zhi Li, Yi Luo +3
Light detection and ranging (LiDAR) has been widely used in autonomous driving and large-scale manufacturing. Although state-of-the-art scanning LiDAR can perform long-range three-…
