Spectacles for viewing colour TV - include polarising sheets to produce three-dimensional image effect

摘要

The viewer uses a simple pair of polarised spectacles for viewing three-dimensional effect films. A second polarising sheet is placed obliquely in front in order to produce an optical effect giving depth to certain colour television images. - The sheet placed in front of one eye may be adjusted. The 3-D effect develops after some minutes of adaptation.(0/0)
