Light Field Copy Machine

This combination of future displays and future cameras copies 4D light fields just as a 2D copy machine reproduces text and images on a sheet of paper. Attendees can use the system to capture light fields and copy "real" objects.  

The system consists of two technical features: 

1. A camera array that uses computational photography to capture 4D light fields.

2. A dense, massive, tightly calibrated cluster of micro projectors that reproduces captured light fields on a wide-field autostereoscopic display.

The project demonstrates how life will change when light-field copiers are available in homes and offices.
