Grace Kuo

I am a PhD student in the department of Electrical Engineering and Computer Science at UC Berkeley, advised by Professor Laura Waller and Professor Ren Ng. I graduated from Washington University in St. Louis in 2015 with a degree in Electrical Engineering.

My research is in computational imaging, which is the joint design of hardware and algorithms for imaging systems. I work at the intersection of optics, signal processing, computer graphics, and optimization.

DiffuserCam: A Diffuser-Based Lensless Camera

project page / PDF / GitHub

DiffuserCam is a lensless camera made of a piece of bumpy plastic, called a diffuser, in front of a bare image sensor. Since there are no other elements in the system, the camera is cheap, compact, and easy to build. Unlike a traditional camera with a lens, the image sensor does not directly record information about the world. Instead, we computationally recover the scene from the measured data. We've demonstrated that our simple system can be used for both 2D photography and 3D image reconstruction.
