Compared with traditional imaging, optical field imaging records the four-dimensional position information and direction information of the object. It has two degrees of freedom more than the two-dimensional traditional image, so it has more abundant

A new method of generating and detecting terahertz waves is proposed. Low-temperature-grown gallium arsenide (LT-GaAs) thin films are prepared by etching a sacrificial layer (AlAs) in a four-layer epitaxial structure constituted with LT-GaAs, AlAs, G
