Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word ''stereoscopy'' derives . Any stereoscopic image is ...

s. KMQ stands for the inventors' initials: Koschnitzke, Mehnert, Quick.
A recent usage of this technique is the openKMQ project.
Principle
An image pair is placed one above one another. The
prismatic viewer tilts the right eyesight slightly up and the left eyesight slightly down.
Stereoscopic viewing is achieved at a matching distance to the glasses. When placing the right view on top of a (letter/A4 size) paper and the left view below, viewing from arm length distance (ca. 50 cm) creates a stereo experience. Bigger over/under stereo image pairs on either paper or a monitor can be viewed from a proportional greater distance. In general, the prisms achieve a 19° viewing angle.
