Most people would think that 3D technology has only been around for the last few decades. It is extremely surprising to find the initial concept was experimented with almost 170 years back! It is incredible to consider that it has actually been around as long as photos and regular 2D motion pictures.
Stereoscopy, today more commonly referred to as 3D imaging, creates one simple principle: Two images are taken from slightly different angles or vantage points. When viewed together, your brain automatically combines the 2 2D images into one 3D image. You will find three ways to present these different images to each individual eye:
• The viewer can wear glasses that combine these two images from two different sources.
• Glasses can be worn that filter two different images in one source.
• The images could be split with a light source directly into the eyes. In this case there is no need for glasses.
The concept of 3d imaging was originally studied and experimented with long ago in 1938, by Sir Charles Wheatstone. He used both lenses and mirrors to make a 3d image. A few years later in 1844, the concept was improved by Sir David Webster. Webster did away using the mirrors and created a design that has changed very little to this day.
In 1861 Coleman Sellers was one of the first individuals to try and project actual moving images in 3D. He would show a sequence of captured still images in quick succession, giving the viewer the illusion of motion.
In 1891, a method using anaglyph images was patented by Louis Ducos du Hauron. When viewed with glasses with two different colored lenses, the anaglyph image is revealed in like a 3d image. This system was the very first passive 3D system. The anaglyph systems normally used green and red lenses, but since 1971 cyan and red have been used.
The first public screening of the 3D film was presented in New York, at the Astor Theatre in 1915. The film was called Jim the Penman, and also used anaglyph technology. Two separate film strips were projected side by side, and the audience were given tinted glasses in order to begin to see the stereoscopic images. The anaglyph technique does have drawbacks, mainly the reality that there’s a slight ghosting effect. In 1952, using polarising filtering lenses this ghosting problem was overcome, and a new trend in 3D technology was born.
Thinking about the humble and primitive beginnings of 3D imaging, it is astounding to live in an age where there is really an explosion in 3D technology. Gone are the days of anaglyph images, as Active 3D glasses took the market by storm. You can even find Bluetooth 3D glasses in order to avoid pesky cords and cables. Samsung continues to be at the forefront of active 3D research and it has bulk of the market share. If you are planning to venture into the 3D realm, be sure you purchase Samsung Active 3D Glasses or at least 3d Glasses Suitable for Samsung.
