OPTICAL SYSTEM CAPABLE OF CREATING THE THREE-DIMENSIONAL IMAGE ON AN OBJECT IN SPACE WITHOUT IMAGE INVERSION

摘要

The optical system comprises a convergent mirror (E c) and aplane mirror (E p), which are duly positioned in order for the focus (F)established in the optical axis (X-X) of the convergent mirror (E c) inturn to be located in the sector lying between both mirrors. An object(I1-I2) located in an area (1) is first reflected onto the plane mirror (E p)and then onto the convergent mirror (E c), yielding an image (I''1-I''2) inan area (2) opposite the area (1) in a normal position for an observerlocated at a point (O) outside the system, i.e. in such a position that thesigns are legible.
