Area of Science:

Photonics
Machine Vision
Biomedical Engineering

Background:

Current machine vision systems lack the adaptive focusing of the human eye.
Scaling traditional sensing methods for high resolution is costly and power-intensive.
Existing systems struggle to emulate the eye's efficiency and resolution.

Purpose of the Study:

To develop a chip-scale LiDAR architecture inspired by the human retina.
To overcome the limitations of rigid parallel-sensing mechanisms in machine vision.
To enable dynamic gazing and efficient resource allocation for high-resolution sensing.

Main Methods:

Developed a retina-inspired chip-scale LiDAR architecture.
Integrated an agile external cavity laser with reconfigurable electro-optic frequency combs.
Enabled coherent LiDAR with parallel, reconfigurable channels for dynamic resource allocation.

Main Results:

Achieved real-time 4D imaging with 0.012° beyond-retinal resolution.
Demonstrated dynamic gazing capability, allocating sensing resources to critical regions.
Showcased hardware efficiency and scalable chip-level manufacturability.

Conclusions:

The developed LiDAR technology offers a path toward lightweight, high-performance perception for autonomous systems.
The retina-inspired design overcomes the bottlenecks of current machine vision.
This technology enables beyond-retinal resolution and dynamic sensing capabilities.
