These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze how Light Field Technology is becoming economic feasible for an increasing number of applications. Light Field Cameras record all of the light fields in a picture instead of just one light field. This capability enables users to change the focus of pictures after they have been taken and to more easily record 3D data. These features are becoming economically feasible improvements because of rapid improvements in camera chips and micro-lens arrays (an example of micro-electronic mechanical systems, MEMS). These features offer alternative ways to do 3D sensing for automated vehicles and augmented reality and can enable faster data collection with telescopes.
