A device for displaying the location of an object relative to three axis intersecting each other perpendicularly in a space, the device comprising: (a) a source of a location signal indicative of the instantaneous coordinates of said object with respect to each of said three axes in said space; (b) means defining a surface and two axes of a system of coordinates in said surface perpendicularly intersecting each other; (c) optical means for projecting an image of a point in said surface, said optical means having an optical axis and a focal length; (d) rotating means for rotating said optical means about an axis of rotation transverse to said optical axis and extending in a common direction with said surface, said axis of rotation being spaced from said surface; (e) first signal generating means for generating an angle signal indicative of the instantaneous angle defined by said optical axis and a line perpendicular to said surface; and (f) second signal generating means operatively connected to said source and to said first signal generating means for producing a visible, luminous signal in said point of said surface when said instantaneous angle assumes a predetermined value, (1) the position of said point relative to one of said axes in said surface being a function of the spacing of said axis of rotation from said surface and of the ratio of the respective coordinates of said object with respect to a first and a second one of said three axes in said space, (2) the position of said point relative to the other axis in said surface being a function of said spacing and of the ratio of the respective coordinates of said object with respect to the second and third axes in said space, (3) said predetermined value being a function of said spacing, of said focal length, and of coordinates of said object with respect to two of said three axes in said space.
