Mechanical scanning systems
Abstract
A definition and a general scheme of scanning are given. A description of the various types of scanning is provided, as well as an explanation of the geometric properties of linear scanning that are relevant to radiometry. The scanning process is classified into two categories: (1) when the scanner is located between the objective lens or mirror and the terrain to be analyzed; and (2) when the scanner is between the objective and the detector. In the section on geometry, the means of image analysis during scanning are detailed and the interpretation of photographic reconstructions is elucidated.
