Abstract
The invention provides a device for linear scanning, including at least one reflecting element whereby an incident beam of light undergoes at least two reflections; at least one optical system comprising an objective capable of forming an image of an object, the objective, depending on the respective direction of the light beam, defining a pre-objective scanning space and a post-objective scanning space; a mounting structure for the at least one reflecting element; drive means for causing the mounting structure to perform a movement; and a light-detecting element for detecting the incident beam of light, or an element for producing light, wherein, with light-detecting, scanning takes place in the post-objective space, and with light-producing, scanning takes place in the pre-objective space.
