An optical instrument for giving to pictures the appearance of solid forms, as seen in nature. It combines in one, through a bending of the rays of light, two pictures, taken for the purpose from points of view a little way apart. It is furnished with two eyeglasses, and by refraction or reflection the pictures are superimposed, so as to appear as one to the observer.
Device for creating a 3-D image of drawn objects. Works by projecting two different images of the objects to the eyes.
a device used to view overlapping photographs to obtain the mental impression of a three-dimensional image, or model.
photo interpretation tool which assists the user in obtaining a three - dimensional view of the landscape. These tools also provide magnification of the images to assist in the interpretation of small objects.
An optical instrument through which two pictures of the same object, taken from slightly different perspectives, are viewed, one by each eye, producing the effect of a single picture with depth. Used with maps.
an optical device for viewing stereoscopic photographs
a device by which each eye can be presented with different images, allowing stereopsis to be stimulated with two pictures, one for each eye
an AC-powered or battery-powered device that combines the images of two similar objects to produce a three-dimensional appearance of solidity and relief
an instrument which makes surfaces look solid
an optical instrument producing an impression of depth or solidity
a viewing device that presents each eye with a slightly different photograph of the same scene, which generates the illusion of depth
a binocular optical instrument for assisting the observer to view two properly oriented photographs or diagrams to obtain the mental impression of a three-dimensional model
Low power binoculars with a 3D viewing device.
Viewer for stereoscopic photographs.
An optical device for creating stereoscopic (or three-dimensional) effects from flat (two-dimensional) images, the stereoscope was first constructed by D.Brewster in 1844. It is provided with lenses, under which two equal images are placed, so that one is viewed with the right eye and the other with the left. Observed at the same time, the two images merge into a single virtual image which, as a consequence of our binocular vision, appears to be three-dimensional.
A binocular optical device for viewing overlapping images to obtain a mental impression of three dimensions.
An optical instrument which presents two slightly different views of the same scene, one to each eye, giving an illusion of three dimensions.
a viewing instrument that uses special lenses and/or mirrors to produce the illusion of depth when looking at pairs of overlapped air photos. A stereoscope makes air photos look three dimensional, allowing for easier identification of elevation changes and landforms.
A device used to look at paired air (aerial) photography, making it possible to see features on the photographs in three-dimensional perspective.
An instrument which has two eyepieces and is used to view stereomodels such that the images from the two photos are combined into one stereo view of that location, showing relief and depth of features.
A binocular optical instrument to assist an observer to view photographs and diagrams to obtain a mental impression of a three-dimensional model.
A device for viewing stereograms, employing prisms, lenses or mirrors to facilitate vision and the fusion of images.
A stereoscope is a device for viewing stereographic cards, which are cards that contain two separate images that are printed side-by-side to create the illusion of a three-dimensional image. This is an example of stereoscopy. When stereographic cards are viewed without a stereoscopic viewer the users are required to force their eyes either to cross, or to diverge, so that the two images appear to be three.
