Super Field-of-View Lensless Camera by Coded Image Sensors

Sensors, 2019
A lensless camera is an ultra-thin computational-imaging system. Existing lensless cameras are based on the axial arrangement of an image sensor and a coding mask, and therefore, the back side of the image sensor cannot be captured.
