Key Insights from the White Paper
- Terahertz imaging operates between infrared and millimeter wavelengths, offering powerful capabilities for see-through and non-destructive inspection across various fields.
- Terahertz radiation is non-ionizing — no X-ray risks.
- INO’s uncooled microbolometer offers broadband sensitivity (90 GHz–20 THz).
- Ultrafast lenses (F/0.6–F/0.7) improve spatial resolution and light collection.
- Resolution depends on wavelength, magnification, and optical design choices.
Frequently Asked Questions
What is the terahertz frequency range?
Terahertz imaging operates in the electromagnetic spectrum between 0.3 and 10 THz, corresponding to wavelenghts of 30 µm to 1 mm.
What materials are transparent at terahertz wavelengths?
Materials such as cardboard, plastic, leather, textiles and certain ceramics are opaque to visible or infrared light but transparent to terahertz wavelengths.
Is terahertz imaging safe for human use?
Yes. THz radiation is non-ionizing, meaning it does not have enough energy to remove electrons from atoms or damage biological tissue. This makes terahertz imaging a safe alternative to X-ray systems.
Can terahertz imaging detect internal defects or hidden features?
Yes, terahertz wavelengths penetrate non-metallic materials making it able to identify hidden objects, internal layers or defects making it ideal for non-destructive testing (NDT), quality control and security inspection applications.
