Stereoscopes

Part of speech: noun

Definitions

1. Instruments designed to view two slightly different images separately to create the illusion of depth and three-dimensional perception ; devices used for examining objects or scenes in three dimensions by presenting dual images for each eye ; optical apparatus that allow visualization of stereoscopic images to simulate three-dimensional effect by merging two perspectives into one
2. Tools that enable seeing two images separately to produce a 3D visual effect ; equipment that presents two distinct viewpoints to each eye for a depth perception experience ; optical devices that combine paired images to give a perception of spatial dimension
3. Viewing devices that present two offset images to create an impression of depth ; equipment employing dual images for each eye to simulate three-dimensional vision ; optical instruments facilitating the perception of three-dimensional scenes through separate images for both eyes

Etymology: "Stereoscopes" is the plural of "stereoscope," a noun formed from two Greek-derived elements: "stereo-", from Greek "stereos" meaning "solid" or "firm," and "-scope", from Greek "skopein," meaning "to look at" or "to examine." Together the parts describe a device for viewing solid, three-dimensional form. The logic of the name matches the mechanism. A stereoscope presents two slightly different pictures, one to each eye, and the brain fuses them into a sense of depth. The "solid" in the first element refers to that perceived three-dimensionality, while the "looking" in the second refers to the act of viewing through the instrument.

Synonyms: viewers, binoculars, 3D viewers, optical devices
