Abstract

The invention discloses a system for improving a terahertz scanning imaging speed. The system comprises a terahertz wave source, a terahertz wave detector, a first beam splitter, a collimating lens, a second beam splitter, a planar metal reflecting mirror, a first chopper, a second chopper, a chopper controller, a first 90-degree off-axis paraboloidal metal reflecting mirror, a second 90-degree off-axis paraboloidal metal reflecting mirror, a two-dimensional electric control displacement table, an electric control displacement table controller, a computer and a data acquisition card. According to the system provided by the invention, the terahertz scanning imaging speed can be doubled at the same scanning speed by virtue of only one continuous terahertz wave source and only one point terahertz detector.

Description

technical field [0001] The present invention relates to the application field of terahertz waves, in particular to a method and system for increasing the speed of terahertz scanning and imaging. Background technique [0002] Terahertz (THz) waves generally refer to electromagnetic waves with a frequency between 0.1 THz and 10 THz (wavelength between 3 mm and 30 μm), and are located between microwave and infrared radiation in the electromagnetic spectrum. THz waves can penetrate many dielectric materials and non-polar materials, such as clothing, plastic and paper, etc., and can perform perspective imaging on objects that are opaque to visible light, and its photon energy is very low and will not ionize organisms, so Hertz imaging is a safe imaging technique. In addition, terahertz waves have shorter wavelengths than millimeter-wave imaging techniques, so they can provide higher spatial resolution. Based on the above characteristics, terahertz wave imaging technology has i...
