What Is 3d Projector? Functionality Of A 3d Projector?

By Arindam Roy

Pico projectors are essentially scaled down versions of their larger kin. Similar to a regular projector, the pico projector is used to project visuals and images onto flat surfaces like walls and ceilings.

Projectors can be used in classrooms, meetings, conferences or for home entertainment needs. Projectors are also used for professional business presentations and meetings.

As projectors are used to display images from computers or other devices, they require a source of light which can enhance the projected image.

These projectors can be considered to be the “smallest of all projectors” hence their name, pico. The term Pico is derived from the word “pix” which was coined by Carl Zwanzig and stands for pictorial imager.

The pico projector is a portable device hence can be carried around easily without any hassle.

Projectors are not only used for projecting purposes, they have found many applications in other fields as well. The projection of a virtual keyboard for example, is used in cell phones as well as mobiles.

Designing pico projectors has attracted a lot of attention among scientists and engineers. The technology behind the projector is very similar to that used in the traditional projector.

The main components include a light engine , an image processor, media input, lens and an output display . The lens is responsible for projecting the light from the bulb onto a specific surface while the processing unit controls most of the other components.

The pico projectors come in different sizes which are categorized by their pixel dimensions ( resolution ) ranging from 800 x 600 to 2000 x 1200 pixels ( XGA ). The image processor is responsible for outputting the correct color for each pixel. The higher the resolution the better quality of image provided.

The light source used in these devices is a light emitting diode ( LED ) which can be constructed from semiconductors. The device converts electrical energy into light energy in order to produce images. Hence, pico projectors are very similar to the regular projectors, with a few alterations and modifications to their components.

Functionality of a 3d projector

A 3D projector is a device that projects 3D images in real time onto a screen or other surface.

In this article, we will discuss the functionality of a 3d projector including: what they are made up of, how they work, and who would benefit from one. Additionally, we will discuss the many different types available such as digital projectors and pico projectors. Lastly, we will conclude with some interesting facts about today’s newest 3d projector technology called 4K.

Functionality of a 3d projector – A new device has been recently released to market which aims to capture the attention of those looking to incorporate this technology into their home or business. This small, compact device is known as the 3d projector. The technology behind a 3d projector is based on the fact that when we view an image, light is reflected back to us through our eyes. Within the eye are light-sensitive cells called rods and cones which process this reflection into images we can see. A 3d projector uses micro-lens technology to project images onto a screen or other surface in such a way as to mimic this reflecting of light. The end result being that what you see on the screen appears to be three-dimensional, giving off the illusion that it has much more depth than it actually does.

How they work – For the 3d effect to work, the projector needs to transmit two images simultaneously; one for each eye. The micro-lenses on the projector then split each of these images into three separate images so that each of the eyes receives a different image. This results in what is called an anaglyph image, which can be viewed by wearing glasses with red and blue lenses which are polarized to ensure that only one image enters each eye.

Who would benefit from one – One area in which 3d projectors have already been used successfully is business and marketing. Corporations go to great lengths to create a more interactive experience for their customers or clients at trade shows and conventions. These trade shows allow for sharing of ideas and the exchange of information between companies and their customers which helps them be more successful. In this environment, a 3d projector can be used to display images on the wall or screen that appear three-dimensional, creating an interactive experience for those attending. This technology has been used to create 3d images of fast food restaurants’ meals where you can take one step forward in order to see more detail or a second step back in order to see the view from farther away.

Types available – Digital projectors are another type which is currently available as a 3d projector product. Digital projectors, in contrast to pico projectors, are designed to produce a full-color 3d image on a screen. While the resolution and size of digital projectors are larger than their pico counterparts, the price is often more affordable.

4K – The most recent development coming from 3D technology is called 4k [Four thousand by two thousand], which is an abbreviation of 4 times the number of pixels used in 1080p video, 2 times the number of pixels used in 720p video, and 1 time the number of pixels used in 480p video. It is reported that this technology is being used in movie theaters and other entertainment venues. This new technology is reported to have a resolution of 8 million pixels, which is around 4,000 pixels per inch. But the most outstanding quality of 4k seems to be it’s ability to display images in 3D on a screen with incredible color and unparalleled detail.

Fun Facts – There are some interesting facts about today’s newest 3D technology. In 2011, 3D movie attendance was at its highest point since the year 2003 with 144 million tickets sold domestically (Screen Rant). In 2011, 43% of moviegoers saw a 3D movie compared to just 19% in 2010 (Action Online). In 2011, the biggest 3D movie was Avatar with 146 million tickets sold, while the smallest 3D movie was Cloudy with a Chance at Meatballs with 44 million tickets sold. These numbers were verified by comScore and IHS Screen Digest.

With all of this technology behind it, there are still those who are skeptical of the 3d effect. The most common argument against using a 3D projector is that there is a lot of focus needed to see it as realistic as possible. If you have trouble focusing your eyes or looking through them for long periods of time, then this device would not work for you.
