1. A device for linear scanning, comprising:

  • a reflecting element selected from the group consisting of a prism and a pair of angle mirrors arranged and adapted so that an incident beam of light undergoes at least two reflections;

    at least one optical system comprising an objective which forms an image of an object, said objective, depending on the respective direction of said light beam, defining a pre-objective scanning space and a post-objective scanning space;

    a mounting structure for said at least one reflecting element;

    drive means for moving said mounting structure in one of a linearly reciprocating motion and a continuously rotating motion; and

    a light-detecting element for detecting said incident beam of light, wherein, with light-detecting, scanning takes place in said post-objective space.
