Digital Image Processing 7

Examples of Fields that Use Digital Image Processing

The principal energy source for images in use today is the electromagnetic energy spectrum.

The electromagnetic spectrum arranged according to energy per photon.

Digital Image Processing 8

Examples of Fields that Use Digital Image Processing

Gamma-Ray Imaging Nuclear medicine and astronomical

observations. In nuclear medicine, the approach is to

inject a patient with a radioactive isotope that emits gamma rays as it decays. Images are produced from the emissions collected by gamma ray detectors.

Examples of Fields that Use Digital Image Processing Imaging in the ultraviolet band Lithography, industrial inspection,

microscopy, lasers, biological imaging, and astronomical observations.

Fluorescence microscopy - an excellent method for studying

materials that can be made to fluoresce, either in their natural form (primary fluorescence) or when treated with chemicals capable of fluorescing (secondary fluorescence).
