1. A confocal fundus scanner, comprising:
a lighting device configured to generate at least one light beam;
a detector capable of emitting a signal when struck by light to form a digital image;
optical units positioned with respect to the lighting device and the detector so as to have the light beam passing therethrough to direct it along an illumination path towards a predefined target position and to send a reflection of that light beam from the target position towards said detector along an image path; and
a scanning device with a movable wall with a first slot positioned to intercept said image path and a second slot positioned to intercept said illumination path wherein:
the first slot is configured and positioned to form from said light beam an illumination light strip with a linear section;
the second slot is configured and positioned so as to form from said reflection a strip of reflected light having a linear section; and
the wall is configured such that as a result of their own movement, the first and second slots are jointly displaced.
