In this compelling episode, Dr. Weijian Yang introduces us to a breakthrough in computational imaging: a compact and learnable lensless 3D camera capable of real-time photorealistic imaging. This technological innovation holds great promise in revolutionizing how we capture and interpret our world.

The device, developed by Dr. Yang and his team, replaces traditional bulky optics with customized thin optical masks, making it lightweight and portable. Contrary to existing lensless imaging methods that require extensive calibration and heavy computational resources, this lensless 3D camera overcomes these challenges. Dr. Yang discusses the custom design and fabrication of the optical phase mask, optimized for spatial frequency support and axial resolving ability.

The team has developed a robust physics-aware deep learning model with an a ...
