Simulation of terahertz light field imaging based on single camera

Terahertz light field imaging is also known as computational imaging, and its acquisition is limited to terahertz camera scanning. Camera scanning light field imaging systems are limited by the performance of the device, and there are problems such as large image noise and small field of view. This paper proposes a single-camera terahertz light field imaging, using Matlab software for system simulation and image processing, reducing output image noise by adjusting simulation parameters, improving image quality, and browning the image to make the outline clearer. Further analysis of the improvement in imaging quality lays the foundation for the development of terahertz light field imaging in refocusing and depth estimation. Finally, it is pointed out that the terahertz band has strong penetrating power in imaging and can play a unique advantage in biometrics, military detection and security.
