Our view of the natural world is constrained to a bandwidth of 400 to 700 nanometers within the electromagnetic spectrum ... each image is separated into its red, green and blue spectral ...

Hyperspectral imaging (HSI) is a state-of-the-art technique that captures and processes information across a given electromagnetic ... full spectrum at each pixel in an image. This rich spectral ...

Terahertz (THz) technology refers to the use of electromagnetic ... making THz imaging a useful tool for non-destructive testing and hidden object detection, as it does not harm humans like X-rays do.

The answer may lie at the other end of the electromagnetic spectrum, in the terahertz region. Terahertz technology makes it possible to perform imaging ... which have no spectral lines in this ...

THz waves, located in the far-infrared region of the electromagnetic spectrum, can be used to perform non-invasive imaging through opaque materials for security and quality control applications.
