A slide projector that combines two images to create a three-dimensional effect, or makes one image dissolve into another.
- ‘What we ‘see’ in a stereopticon is neither of the images at which we are actually looking.’
- ‘Instead he encountered a stereopticon that presented a type of slide show of Italy, ‘dancing girls and all.’’
- ‘Indeed, this masterful handling of imagery also furnishes a narrative version of a stereopticon.’
- ‘These two men represent diversity rampant, united only by their gender and individuality of vision, like a mismatched stereopticon instead of duplicate images, right and left.’
