High speed macro 3D portable unit with optical extern focus detector using 2 DSLR camera's and front side type mirrors.

First pictures of the portable 3D setup. The picture show only the mechanics parts. The electronic box need to added into the next days. This unit is realy difficult to make. There are a lot of fine pices to calibrate. The 2 camera's D300 and D200 are inline and can be adjusted direction mirrors. This is needed because the AF105/2.8D macro lenses d'nt have a fix lenght. The mirrors can be moved into the other direction on a slide. On top of this slide there are the 2 mirrors. They can turn a little to adjust for the keystone effect and to center the pictures on the frame. At the bottom on each side the IR lasers are mounted. The IR lasers can turn into X-Y-Z direction and are finetuned via separate screws. On the top of the unit the AF60/2.8D macro lens record the reflected IR lasers signal from the objects infocus. Into the body of this macro lens there is the AVR controller circuit to measure this IR light. This information goes to the central hardware controller for further action.
The 2 mirrors are protected for most of dust via the 2 nikon 62mm diameter filters. Just near this filters there are 2 powerleds to work at night. The 2 flashes are on the top and on both side there are the green lasers. The green lasers are used for me to point the unit to the objects. Even in full sunlight is see this green pointers. They are crossed mounted into the ideal focuspoint. The IR lasers are also crossed on this same point.

On the otherside I have mounted an optional calibration slide tool. The testcard stay on this slide at the correct position and can be moved forwards and backwards. The textcard is used to calibrate the hole unit and to adjust them for the desired frame format. Moving the testcard d'nt change the high of the object, so this is a very helpfull tool to adjust and calibrate the hole unit.

The weight of the unit is near 8.5kg inclusief the electronics parts. This is very heavy to carry into the field but the results of this hightech detection system and 3D are so promising. I try now to cut down as many as possible alu parts to lower the wight. But the unit must stay stable. The load into the field is very heavy for all the parts.

    Dat ziet er schitterend uit Frans. Baanbrekend werk.
    Een dikke proficiat en laat ze nu maar vliegen.....

    Jamaar eerst nog de electronica afwerken. Maar de meeste mechanische delen zijn toch gedaan en afgeregeld. Met een beetje geluk moet alles toch werken tegen de tweede helft van maart. Maar het ziet er veel belovend uit.

    Is wel heel druk op mijn Flickr de laatste tijd. In een week tijd zijn meer dan 600.000 clicks geweest.
    Maar we doen verder.
