This document discusses the science behind stereoscopy and 3D imaging. It begins with an introduction to stereoscopy and how it creates an illusion of depth by presenting two offset images separately to each eye. Next, it explains how binocular vision allows our brain to perceive 3D from these 2D images by overlapping the fields of view from each eye. Then, it contrasts normal images, which both eyes see the same, with stereoscopic images, where each eye sees a slightly different image to create the perception of depth. The document proceeds to describe several stereoscopic techniques throughout history and modern applications such as 3D movies, TV, cameras and more. It concludes that stereoscopy is a rapidly progressing field used across entertainment, medical and

3. Introduction
- 3-D Imaging.
- Technique for creating illusion of depth by means of Stereopsis.
- Most stereoscopic methods present two offset images separately to the left
and right eye of the viewer. These two-dimensional images are then
combined in the brain to give the perception of 3D depth.
4. Binocular Vision
- The brain uses several tricks to make us see in three dimensions.
- Despite our 180 degree field of view, binocular vision is only possible in the
area where the view from both eyes overlap.
5. Stereoscopy Vs. Normal Image
- In a normal image both of our eye sees the same picture.
- But in a stereoscopic Image our two eyes sees two slightly different images,
and that’s how illusion of three-dimensional depth is created.
18. Conclusion
- We can say that Stereoscopy is one of the most progressing field in todays
world.
- Stereoscopy is used in almost all variety fields from Entertainment to
Medical Sciences, etc.
- Looking at the progress in research and the upcoming technologies we can
say that within a time of few years people will be living in virtual world which
is one of the biggest drawback but it will be very helpful in simulation and
virtual reality to test new researches.

Editor's Notes
More modern choice for cheap 3dAllow color viewing .Two synchronized projector project two respective view onto the screen, each with a different polarization.The glasses allow only one of the image into each eye because they contain lenses with different polarization.The brain does the hard work again , combining two separate image into a single 3D one.Used in most of today 3D theaters
Used at HOME THEATER.Image Looks Great.There is a battery in it.The TV rapidly flash alternating left-eye and right –eye video frames at 120 times per second.Through the glasses you will see a one picture for each one at time , But the left/right video image.Alternate so quickly that you perceive a full, three alternate so quickly that you perceive a full, three-dimensional view…AFS:ITS COSTY..ACTIVE 3D NEEDS TO BE CHARGE BEFORE USE..THEY R HEAVY IN COMPARISION OF ACTIVE 3D.PEOPLE COMPLAIN ABOUT HEADACHE .
A 3D or 3-D (three-dimensional) film or S3D (stereoscopic 3D) film is a motion picture that enhances the illusion of depth perception. Derived from stereoscopic photography, a regular motion picture camera system is used to record the images as seen from two perspectives (or computer-generated imagery generates the two perspectives in post-production), and special projection hardware and/or eyewear are used to provide the illusion of depth when viewing the film. 3D films are not limited to feature film theatrical releases; television broadcasts and direct-to-video films have also incorporated similar methods, especially since 3D television and Blue-ray 3D.
3D ultrasound is a medical ultrasound technique, often used during pregnancy, providing three dimensional images of the fetus..SAMSUNG ELECTRONICS:: Massive headache, eye stress…!!TOSHIBA::”Due to the possibility of impact on vision development , viewers of 3D video images should be above 6 years‘….”Watching TV for long time is not good ..Some risk 6 or 8 while using NINTENDO 3DS “potential impact on growth of children eyes” PC MAC, FOX.Can effects older people in different ways..Very little research is done on EFFECTS OF 3D VIEWING ON CHILDREN ADULTS
