The system and method achieves the actual application of the technology of terahertz wave rapid rotation scanning imaging, successfully improves the imaging speed and effect, and is of great significance to the development and popularization of the technology of terahertz wave rapid rotation scanning imaging.

Description

technical field [0001] The invention belongs to the technical field of application of semiconductor optoelectronic devices, in particular to a terahertz wave rapid rotation scanning imaging system and method. Background technique [0002] THz (terahertz) imaging is one of the important application directions of THz technology. THz radiation refers to electromagnetic radiation with a frequency in the range of 0.1 to 10 THz. Since THz waves have a smaller scattering extinction coefficient than infrared, THz waves are significantly different from infrared and microwave in terms of propagation, scattering, reflection, absorption, and transmission. features. THz waves have good penetrability to non-polar materials (such as cardboard, plastic, ceramics, foam materials, etc.), and can detect hidden contraband; THz photons have small energy and will not cause photoionization of biological tissues. Suitable for biomedical imaging; THz radiation imaging has high resolution, good ima...
