What are the two types of scanning technology?

The two types of scanning technology commonly recognized in the context of imaging are optical and digital technology. Optical technology refers to the methods used to capture images through capturing light reflection, commonly used in devices like scanners and cameras. Digital technology encompasses the processing and storage of these scanned images in a digital format.

Interlacing technology and progressive technology pertain specifically to video display techniques, describing how images are rendered on screens, rather than scanning technology itself. Interlacing involves displaying alternating lines of an image in sequence, while progressive scanning displays all lines in a single pass.

In terms of scanning, the more relevant categories are technologies that capture and process images, which do not include interlacing and progressive as distinct types of scanning technology. Thus, the correct emphasis is on the optical and digital aspects that directly relate to scanning methods and their resulting outputs.
