Prototype1 is ready
See Pictures below.
The construction got a bit bigger than expected, but it will do as a proof of concept. I added a handle for testing, I only tried shortly and unsuccesfully to attach it to a head light. One screw is not tight, so I can adjust the angles.
I first tested it out in reality and the hyperscopic effect is quite nice. Increased depth perception in real life is something you guys should try.
Dual CRT Setup
I adjusted the mirrors so when looking straight at my left 19" CRT, my right eye was seeing the right 21" CRT in the mirrors.
I first had to overcome the additional difficulty of matching the screen sizes - unnecessary with 2 identical displays. I used a monitor test picture.
Findings
-allowed movements: any translation or the rotation around horizontal axis(looking sideways) will change nothing.
-movements changing alignment:
pitch(look up/down)-rotate screen
roll (lean left/right)-move screen up/down
The last to movements can easily be avoided, you can freely change the sitting position as long as you keep your head level. They can also be used to compensate for nonperfect mirror alignment - I think this was only neccesary with my loose screwed prototype1.
3D game test
I chose Flatout - a racing game I could control with one hand, the other one was holding the construction.
The effect is really nice: bright clear pictures as expected, only this time steady, as the mirrors were fixed to eachother.
I played for like 30min with no ill effect. I can safely that I prefer the picture over my shutter glasses.And there is no eyestrain as with extreme crosseyed viewing (only handstrain with my prototpe
).
When you pitch your head the images seperate, so you just pitch back, which happens quite naturally.
issues
Ghosting. As you can see in the last picture (upper half), there is some ghosting. Less than with shutter glasses and closer to the origin. There are 4 ghosts: 2 bright ones seen in the picture. Horizontally displaced by maybe 3mm. 2 dim lines another 3mm away.
This ghosting can be avoided. It is caused by two reflections: one intended at the metallic layer, one unintended at the glass surface.
There are 2 Solutions:
-using prisms. All my prisms are ghost free, but for a good field of view (not necessary for this setup), one has to use bigger prisms which will become heavy.
-using first surface mirrors (aka front surface mirror). It seems there is a cheap DIY way:

Anyway it is quite promising. So promising that I am going to buy a ATI graphics card. Before I wanted to buy a inferior nvidia, just to keep all possibilities (more zalman support, 3D Vision) open.
The next steps will be either buying a ready made device (such as in Okta's link above) or building an improved version with front surface mirrors, either DIY or I will ask at my nanooptic department if they have mirrors to spare.
