DiffuserCam: Multi-Dimensional Lensless Imaging

Seminar | April 21 | 2-3 p.m. | 277 Cory Hall

Speaker/Performer:  Prof. Laura Waller, UC Berkeley, EECS

Sponsor:  Berkeley Nanosciences and Nanoengineering Institute

We describe a computational camera that enables single-shot multi-dimensional imaging with simple hardware and scalable software for easy reproducibility. We demonstrate compact hardware and compressed sensing reconstructions for 3D fluorescence measurements with high resolution across a large volume, hyper-spectral imaging, and temporal super-resolution – recovering a video from a single-shot capture.

Our inverse algorithms are based on large-scale nonlinear non-convex optimization combined with unrolled neural networks. Applications demonstrated include whole organism bioimaging and neural activity tracking in vivo.
