Abstract

The invention discloses a terahertz imaging device and method. The terahertz imaging device comprises a collimation module, a masking module and a reflected wave acquisition module. The collimation module is used for collimating incident terahertz signals and then enabling the terahertz signals to irradiate the masking module and an object to be imaged. The masking module is used for covering the part in front of the object to be imaged to control the irradiation region, irradiated by the terahertz signals, of the object. The reflected signal acquisition module is used for acquiring the reflected terahertz signals obtained after object transmission and converting the reflected terahertz signals into electric signals to be sent to a signal processing module. The signal processing module is used for controlling the masking module to move and conducting object imaging according to the corresponding electric signals.

Description

technical field [0001] The present invention relates to the field of terahertz (TeraHertz, THz) technology, and in particular to a terahertz imaging device and method. Background technique [0002] With the development of terahertz technology, the technology of using terahertz time-domain spectroscopy for imaging has attracted more and more attention. The traditional terahertz time-domain spectroscopy imaging technology is to place the sample at the focus of the terahertz spot and move it through a two-dimensional translation stage. sample, collect the terahertz spectrum of each pixel. Finally, the corresponding algorithm is used to restore the terahertz image. This imaging method can simultaneously obtain the spectral information and image information of the sample, which is a spectral imaging method. The disadvantage is that due to the need to scan each pixel one by one, the imaging speed is relatively slow. Generally, it takes 1024 sampling points to collect a terahert...
