Last year I scratch-built a structured light scanner using the David-Laserscanner software, an LED projector, a Point Grey Chameleon 1.3 MP Mono USB 2.0 camera, and a nice Fujinon lens. After a few months of experimentation, with pretty decent results, I added a Proxar A28.5mm .2m Close Up Lens (Carl Zeiss Ikon Proxar Four A28 5 Close Up Lens Slip on Set in Case | eBay) to the front of the camera lens and was blown away by the incredible increase in resolution of the camera image and scans. I ultimately ditched the project because the process of manually positioning the model, and manually fusing the scans took too long.
Here's my question... for those of you scanner gurus who have a scanner opened up for experimentation..... wouldn't it be possible to just add one of these closeup lenses to the front of a scanners' camera lens, reposition the cameras a bit closer to the model so the image is in focus and have vastly improved scan resolution? There's the possibility of slight distortion, but for single units and short-span bridges, wouldn't this be a viable option?
Here's a sample scan I got using my scratch-built setup with the closeup lens on the front of the camera lens:


Nice detail, right! I have two of these closeup lenses and would be willing to loan them out to someone willing to test out this theory. What do you think..... viable or not?
