The Miniature Light-Field Camera with High Spatial Resolution

We propose a new type of microlens array for the light-field camera. The microlens array consists of a large microlens at the center to improve spatial-frequency resolution and surrounding microlenses to provide field-angle information. A PDMS microlens array is fabricated by using nanoimprint technology. Via the proposed microlens array, we can simultaneously obtain field-angle information and high spatial resolution images with a oneshot image.
