Abstract

We show an integrated three-dimensional (3D) imaging device to acquire volumetric object features through a single exposure on the camera sensor. The system uses a single piece of randomly positioned microlens array as a multi-channel light encoder and a hybrid 3D reconstruction algorithm to achieve compact device footprint and low computational complexity. We validate the system in both simulation models and experiments with resolution targets and fluorescent samples. Our system is capable of volumetric imaging across a volume of 1800 mm3 with a high space-frequency bandwidth. It opens new avenues for miniaturized and implantable imaging device for biomedical applications.
