Abstract
The present disclosure provides a light field imaging system by projecting near-infrared spot in remote sensing based on a multifocal microlens array. The light field imaging system includes a near-infrared spot projection apparatus () and a light field imaging component (), where the near-infrared spot projection apparatus () is configured to scatter near-infrared spots on a to-be-observed object to add texture information to a target image, and the light field imaging component () is configured to image a target scene light ray with additional texture information. The present disclosure can extend a target depth-of-field (DOF) detection range, and particularly, reconstruct a surface of a weak-texture object.
