The device comprises: a housing (2) that can be put on an object; a mirror (6) mounted within the housing (2), a camera (7) of the CCD type following the mirror, comprising firstly a focussing member (8) in the form of a sliding part being movable according to a line (10) extending almost parallel to the bottom plane (4) of the housing and being rotable simultaneously with the sliding movement, and secondly a camera housing (9) coupled to said focussing member (8) by means of threading, which housing can not be rotated but can only be moved in the direction of the axis, in which the signals of the camera (7) are transmitted, possibly through a computer, to a display (20).
