Abstract

The invention discloses an integrated terahertz confocal imaging device and imaging method based on a waveguide structure, and belongs to the field of terahertz confocal imaging. The device comprisesa terahertz radiation source, a terahertz waveguide tube, a terahertz semi-transparent semi-reflective mirror, a terahertz focusing lens, an imaging sample, a metal pinhole, a terahertz detector, a data collection card and a computer. By use of the device, a discrete device in a traditional light path is integrated in terahertz waveguide, the terahertz confocal imaging device is compact in integration, and therefore, the problems of complex structure and large volume in an existing terahertz confocal imaging technology can be solved, the high-resolution three-dimensional imaging of the samplecan be realized, richer information in the imaging sample is obtained, and the device has a wide application prospect in fields, including nondestructive testing, biomedicine, safety inspection and the like.

Description

technical field [0001] The invention belongs to the field of terahertz confocal imaging, and in particular relates to an integrated terahertz confocal imaging device and an imaging method based on a waveguide structure. Background technique [0002] Terahertz (Terahertz, THz) wave refers to the frequency of 0.1-10THz (1THz = 10 12 Hz) electromagnetic wave, the corresponding wavelength range is 0.03-3mm, which is between microwave and infrared wave in the electromagnetic spectrum. [0003] Terahertz waves cannot penetrate polar materials such as metals and water, but have good transmission characteristics for non-polar materials such as plastics and clothing. At the same time, terahertz waves have low photon energy and will not cause ionization damage to samples , These superior characteristics make terahertz imaging technology have great application prospects in the fields of non-destructive testing, security inspection, and biomedicine. [0004] Terahertz confocal imaging...
