Abstract
A transmission optical system includes a plurality of imaging optical systems arranged apart from each other, forming successively the image of an object to be projected so a real image of either a two-dimensional or a three-dimensional object can be observed at the opposite end, with its convexity features either identical to or reversed from the projected object, depending on whether the total number of the imaging optical systems is even or odd.
