Layer-Resolving Terahertz Light-Field Imaging Based on Angular Intensity Filtering Method

Terahertz focal plane array imaging methods, direct camera imaging and conventional light field imaging methods are incapable of resolving and separating layers of multilayer objects. In this paper, for the purpose of fast, high-resolution and layer-resolving imaging of multilayer structures with di...
