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.
Claims7
A transmission optical system, comprising:
- a plurality of imaging optical systems, each having an optical device plane,
- wherein light paths of light passing through said optical device plane are bent,
- wherein an object to be projected or its image is placed in front of one side of the optical device plane, whose image is projected as an image at the other side of the optical device plane in a plane symmetric manner with respect to the optical device plane,
- wherein said plurality of imaging optical systems are arranged with distances with each other,
- wherein at least one adjacent pair of said imaging optical systems are arranged in a non-parallel manner.
