A flexible sheet camera: A radically different approach to imaging

The Columbia team, which includes research engineer Daniel Sims BS’14 and postdoctoral researcher Yonghao Yue, designed and fabricated a flexible lens array that adapts its optical properties when the sheet camera is bent. This optical adaptation enables the sheet camera to produce high quality images over a wide range of sheet deformations. Sims will present the work at the International Conference on Computational Photography (ICCP) at Northwestern University in Evanston, IL, May 13 to 15.

 

“Cameras today capture the world from essentially a single point in space,” says Nayar. “While the camera industry has made remarkable progress in shrinking the camera to a tiny device with ever increasing imaging quality, we are exploring a radically different approach to imaging. We believe there are numerous applications for cameras that are large in format but very thin and highly flexible.”

 

If such an imaging system could be manufactured cheaply, like a roll of plastic or fabric, it could be wrapped around all kinds of things, from street poles to furniture, cars, and even people’s clothing, to capture wide, seamless images with unusual fields of view. This design could also lead to cameras the size of a credit card that a photographer could simply flex to control its field of view.
