An imaging device for superimposing two projection images, in particular two perspective views of a three-dimensional object

摘要

An imaging device for superposing a first and a second light projection partial image of a light projection frame, a first projection sub-image deflection device (2A) being arranged in the beam path (A) of the first projection partial image and / or a second projection sub-image deflection device (2B) being arranged in the beam path (B) of the second projection partial image, with the aid thereof the beam path (A) of the first projection partial image and / or the beam path (B) of the second projection partial image can be deflected in such a way that both projection partial images can be superimposed, a first polarization filter (3A) being arranged in the beam path (A) of the first projection partial image and wherein in the beam path (B) of the second projection partial image, a second, to the first polarizing filter (3A) complementary or orthogonal polarization filter (3B) is arranged and wherein a distortion optics (1) in the beam path (A) of the first and / or in the beam path (B) of the second Projektionste ilbildes is arranged to compensate for the superposition due to deflections of the beam paths (A, B) of the light projection part images resulting aberrations or distortions of the projection part images, characterized in that a surface f (x, y) of the distortion optics (1) in two mutually perpendicular Directions (x, y) is parabolic.
