Wheatstone stereoscope

A stereoscope is composed of two pictures mounted next to each other, and a set of lenses to view the pictures through.  Each picture is taken from a slightly different viewpoint that corresponds closely to the spacing of the eyes.  The left picture represents what the left eye would see, and likewise for the right picture.  When observing the pictures through a special viewer, the pair of two-dimensional pictures merge together into a single three-dimensional image.

Brewster stereoscope

It is a lenticular stereoscope (lens based). This allowed a reduction in size, creating hand-held devices. Brewster utilized lenses to combine the two dissimilar pictures and produce the three-dimensional effect.
