3D Projectors

In order to view an image as three-dimensional, our eyes will view things from two slightly different perspectives and then our brains will interpret the difference. Basically 3D projection is a process of viewing two images of the same subject matter, but from slightly different perspectives. We as the viewer will see these projected onto a screen and will typically have to wear specific glasses to view these correctly. 3D projectors can display images that are either photo, video or real-time computer-generated.

There are several different types of 3D projection. The first is described as active stereo projection which is achieved when a 3D projector shows both the left and right are images in a single frame. You will usually find an infrared emitter that is connected to the projector will send a signal to a set of active stereo glasses that you should be wearing. These glasses will have LCD shutters in them and will alternately blank the left and right eyes to ensure you are able to view the correct image.

There is also passive 3D projection. This is where one 3D projector displays the information that the left eye requires and another projector will display the information that the right eye requires. Both projectors will have a standard refresh rate. You will find that a polarising filter will be mounted in the optical light path of each projector. This will ensure that the correct information passes through the corresponding filter into a pair of passive stereo glasses.

There are many reasons that you may choose to view things in 3D or via 3D projection. 3D projection obviously provides a third dimension or “depth” to an image. This, of course, cannot be viewed via normal 2-D projection. This will allow you to understand the image that you are looking at far better and is often used to make quick decisions and in problem solving. Although we most commonly assume that 3D projectors are used in cinema halls and classrooms, they also have a huge impact on many industries.

One of the most common uses of 3D projection is in the oil and gas industry. This has actually enabled this industry to facilitate a huge reduction in the multi-million dollar test drills that were previously required. Prior to the use of 3D projectors and 3D projection, they often require 10 test drills before oil was finally discovered. However, nowadays most test drills will strike oil within the first 2 to 3 hits thanks to the new technology that is 3D projection.

3D projection is also used for the design and manufacturing of cars, aircraft and mass transit. You may already be aware that many public spaces such as museums, planetariums, shows and visitor centers will entertain the viewing public via the use of a 3D projector. This will, of course, make the visual experience far more fulfilling and exciting. We should not forget that 3D projection is also extremely important within architectural design, construction and for various uses within the military.

A typical 3D projection system will involve the use of a 3D projector, certain cabling, emitters that will very much depend on the technology being used, and in most cases a set of 3D glasses. There are far more advanced and complex 3D projector systems that have been designed to include multiple source display, switching, audio and control systems.

The use of 3D projection, and indeed 3D projectors, has now been brought into our homes. There are numerous manufacturers of 3D projectors that realize many consumers would now like the theatre experience to be brought directly into their front rooms. There are numerous makes, models and manufacturers of 3D projectors and they can vary in price. Many of the most basic models can be purchased for under $500, whereas some of the more advanced models will cost many thousands of dollars.

Amongst the least expensive 3D projectors in the marketplace are the numerous models produced by Acer. They have a specific model which is the ace are X1161-3D SVGA which will showcase a highly detailed projection performance, not only onto a projection screen, but even directly onto colored walls. This model yields great energy savings and is extremely easy to setup with their handy installation utilities. This model of 3D projector can be purchased from numerous retailers for under $400.
