Terahertz imaging

Terahertz waves have good penetration through many dielectric materials and non-polar substances, and can perform perspective imaging on opaque objects, making them an effective supplement to X-ray imaging and ultrasonic imaging. It not only allows dangerous goods to be exposed, but also helps surgeons perform visual analysis and assist in cellular pathology diagnosis during surgery, safeguarding our health.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Terahertz (THz) is one of the units of fluctuation frequency, also known as terahertz or terahertz. Equivalent to 1000000000000Hz, usually used to represent the frequency of electromagnetic waves. Due to its high resolution, low energy level, and penetration characteristics, terahertz is highly suitable for imaging and material detection scenarios. a) High resolution: The pulses of terahertz lasers are in the picosecond range, which can achieve high temporal resolution and can be used for research on biological samples with high temporal resolution. High spatial resolution can be used for high-resolution imaging; High resolution Doppler frequency can be used for velocity measurement and target detection. b) Low energy: The photon energy of terahertz is only millielectronvolts, less than one percent of the energy of X-ray photons, and does not produce ionization effects that damage the substance being detected. c) Penetration: Terahertz radiation has a strong ability to penetrate non-metallic materials, making it suitable for everyday applications.
