Frequency Domain Terahertz Coherence Tomography (FD-CT)
- 技术优势
- Frequency-domainmethod is more efficient than existing time-domain methods.THzradiation allows for a deeper look into objects than shorter wavelength IR andvisible devices currently used.THzradiation is non-ionizing and safe to use.
- 详细技术说明
- A technique for detecting and imaging subsurface structural layers utilizing afrequency domain combined with THz radiation (FD-CT).
- *Abstract
-
- *Background
- Detecting andimaging devices are widely used today in the fast-growing security and medicalindustries. Currently, a majority of radiation detecting and imaging devicesare based on a system utilizing a Michelson interferometer and a visible or IRradiation source. However, these existing forms of tomography cannot penetratesurfaces deeply enough when compared with terahertz (THz) radiation. Timedomain THz coherence tomography exists, however it is too slow for manyapplications. A more efficient tomography device that is able to penetrate todeeper layers of an entity is needed.
