Which of the following doesnt indicate the purpose of stereoscope? [6] A rival of Wheatstone, Brewster credited the invention of the device to a Mr. Elliot, a "Teacher of Mathematics" from Edinburgh, who, according to Brewster, conceived of the idea as early as 1823 and, in 1839, constructed "a simple stereoscope without lenses or mirrors", consisting of a wooden box 18 inches (46cm) long, 7 inches (18cm) wide and 4 inches (10cm) high, which was used to view drawn landscape transparencies, since photography had yet to become widespread. By the term mirror we mean a shiny piece of glass, that is polished from the back, which reflects a clear image of the object, placed in front of it. In two successive photos taken in position L1 and L2 separated by a distance equal to the air base B, and the object height is h; a and b are the top and bottom of the object (Fig. Although more recent devices such as Realist-format 3D slide viewers, the View-Master or virtual reality headsets are also stereoscopes, the word is now most commonly associated with viewers designed for the standard-format stereo cards that enjoyed several waves of popularity from the 1850s to the 1930s as a home entertainment medium.

A typical stereoscope provides each eye with a lens that makes the image seen through it appear larger and more distant and usually also shifts its apparent horizontal position, so that for a person with normal binocular depth perception the edges of the two images seemingly fuse into one "stereo window".

Lesser the parallactic angle higher the objects depth. Proper filming and advanced camera technology eliminates many potential problems. A simple stereoscope is limited in the size of the image that may be used. Using positive curvature (magnifying) lenses, the focus point of the image is changed from its short distance (about 30 to 40cm) to a virtual distance at infinity. Use of a stereo pair: A stereo pair consists of two consecutive photographs (A, and B) having a certain percentage of overlap, and these are placed in the manner in which they were taken during the mission; otherwise a pseudo- stereoscopy is obtained. In fact, higher resolution images are possible with monoscopic VR as opposed to stereoscopic VR. This is especially true of stereoscopic VR.

The Wedding ring guards the engagement ring, The lights are out and gone are all the guests. In mirror stereoscope mirrors are used. It demonstrated the importance of binocular depth perception by showing that when two pictures simulating left-eye and right-eye views of the same object are presented so that each eye sees only the image designed for it, but apparently in the same location, the brain will fuse the two and accept them as a view of one solid three-dimensional object. To achieve good stereoscopic vision the distance of the two straight lines should be equal to the intraocular distance y. When showing several pictures taken with 7cm or 8cm you would never find out what stereo base was used for particular picture.

In 1838, Sir Charles Wheatstone described his design of the first stereoscope he had built as early as 1833. Should use the nadir in less than vertical photos, but difficult to define. Stereoscopic vision is constructed with a stereopair images using the relative orientation or tilt at the time of photography. On the other hand, Lens is a transparent piece of glass, with a spherical surface, that concentrates or disperses the rays of light falling on it. different elevations have been topographically displaced by different amounts

Locate your subject in the middle of the frame and take a shot. 3.5) provides a continuously variable
In real life, obviously we see a slight different perspective from each eye. The microscope magnifies the image of the specimen much larger than the stereoscope.
This allowed the study of the effect of interocular difference on the perception of the third dimension by effectively changing the distance between the eyes up to a meter or more. The belt can usually hold 50 paper card or glass stereoviews, but there are also large floor standing models for 100 or 200 views.

On the other hand, Lens is a transparent piece of glass, with a spherical surface, that concentrates or disperses the rays of light falling on it. Otherwise, points identifiable in the photo and a topographic map should be taken for identifying directions. It can be plane or curved. Simplest 2. Monoscopic or monocular vision refers to viewing surrounding objects with only one eye. FLIGHT PLANNING: In order to obtain stereo pair every part of the ground to be surveyed must be photographed at least twice. Vertical exaggeration

Turning a crank (or pushing down a lever) will lift a slide from the tray and brings it into viewing position. WebLens (or pocket) stereoscope has a limited view and therefore restricts the area that can be inspected where as in mirror stereoscope has wide view and enables a much larger area to be viewed on the stereo- pair. A stereoscope is used in conjunction with two aerial photographs taken from two different positions of the same area, (known as a stereo-pair) to produce a 3-D image.
