Passive 3D Projection – Part 8
This post continues the series of blogs discussing do-it-yourself (diy) passive 3D projection systems that use two conventional front projectors. In my previous blogs of this series the discussion has focused on passive 3D projection system that use polarized light as the means to separate the right from the left images that make up the stereoscopic image pair that creates the 3D effect. This new blog starts the discussion on the use of dual projector system that uses color bandpass filtering (i.e., “wavelength multiplexing”), instead of polarization, as the means to separate the right from the left images. In simply terms, wavelength multiplexing, uses two projectors equipped with filters that pass only very narrow bands of colors within the visible spectrum with one of the filters passing a set of colors that is slightly offset in wavelength from the set of colors passed by the filter being used on the second projector. The viewers then must wear passive 3D glasses whose lenses are filters that pass narrow bands of the visible spectrum that matches those being used on the two projectors.

Passive 3D Projection – Part 5
This is Part 5 of a series of blogs discussing passive 3D projection systems.
For these blogs I am focused on passive 3D systems that use polarization as the means to separate the right from the left images. Previously I discussed (in Part 3 – HERE) the role of the 3D Source, the 2-way HDMI Splitter and the 3D Processors. In my most recent blog (Part 4 – HERE) I discussed the different types of polarization, sources for polarizing filters, and projectors with non-polarized light output. Also in these earlier blogs I discussed some general characteristics to consider when selecting the projectors to be use for a do-it-yourself (diy), dual projector passive 3D setup. For this 5th installment of this series, I am discussing the use of projectors that inherently project polarized light and how these can be used in a diy 3D passive linear polarized dual projector system.

Passive 3D Projection – Part 4
This is Part 4 of a series of blogs discussing passive 3D projection systems.
The current discussion is focused on passive 3D systems that use polarization as the means to separate the right from the left images. Previously I discussed (in Part 3 – HERE) the role of the 3D Source, the 2-way HDMI Splitter and the 3D Processors. Also in that earlier blog I discussed some general characteristics to consider when selecting the projectors to be used for a do-it-yourself (diy), dual projector passive 3D setup. For this part of the series I continue the discussion by providing specific details for making the selection of a suitable pair of projectors. Read the rest of this entry »
Passive 3D Projection – Part 3
This blog is a continuation of my previous discussion on passive 3D projection (HERE). Specifically, this blog is focused on do-it-yourself (DIY) dual projector passive 3D projection systems using polarization as the technique to separate the right from the left images. Future blogs will discuss DIY 3D passive dual projector systems using other technologies. Read the rest of this entry »
