Description:

‘Image volumes’ refer to realizations of images in other dimensions such as time, spectrum, and focus. Recent advances in scientific, medical, and consumer applications demand improvements in image volume capture. Though image volume acquisition continues to advance, it maintains the same sampling mechanisms that have been used for decades; every voxel must be scanned or captured in parallel and is presumed independent of its neighbors. Under these conditions, improving performance comes at the cost of increased system complexity, data rates, and power consumption.
This talk describes systems and methods with which to efficiently detect and visualize image volumes by temporally encoding the extra dimensions’ information into 2D measurements or displays. Some highlights of my research include video and 3D recovery from photographs, and true-3D augmented reality image display by time multiplexing. In the talk, I show how temporal optical coding can improve system performance, battery life, and hardware simplicity for a variety of platforms and applications.
