I?ll try it this week and post results 
Do you think the results (Improvements in the n? of points detected) is worth the money investment ?
Do you use more than one strobe light projector for the sides of the head ? or just one ?
- I?ve been thinking on using it because some girls have a really smooth skin, this would cause problems.
Thank you!
Yes, I do think it can be helpful, especially on objects that are smooth and lack features and would otherwise fail, such as smooth skins and fabrics.
I would suggest that you try using strobes first... see what results you get as it will produce the same if not better results than the projector at a fraction of the cost.
Like I said, the only downside of the strobe is that setup is a serious pain, but if you have a studio where you can leave things set up, then once you have everything working, you can leave it be.
One tip, getting the focus just right can be made easier if you shine a bright light (such as a flashlight /torch through the camera back/slide transparency in very dark room onto your test subject. This will make it easier for you to get the lens in focus initially..which is really the most difficult part of using a strobe based projector.
Regarding multiple projectors, I've collected many of them over the years. The answer is yes, I generally use multiple projectors, so that at least 180 degrees can be covered at once.
If you have 4 projectors you can place them at each corner of the room and assuming that your subject is placed in the center all beams can converge for 360 degree coverage.
Regarding the washing out of your diffuse textures, the solution to this is to have your system fire twice. What I mean by this is that you can first take a shot with the speckle pattern being projected and then a split second later, take another this time with the projection muted. The second shot will NOT have patterns projected and this can be used for your texture. Provided that the subject doesn't move much it will work. The key to this is to have the 2nd shot fire as fast after the first as possible. To do this you will need to use some sort of flash delay control device (such as the camera axe or pocketwizard max). This can also be done with dlp projectors, but a custom shutter system will have to be constructed, either electronic or mechanical.
I hope this will give you some ideas :-)
Good luck with everything and please post your results so that others can learn from your experience.
