It can collect data with high accuracy. These data can be used in reverse engineering and point cloud. Onsite3D provides the best 3D laser scanning service in Houston, Texas. <a href="https://onsite3d.ca" rel="nofollow">Best 3D laser scanning service Houston, Texas</a>JM Craftshttps://www.blogger.com/profile/18019284883736917466noreply@blogger.comtag:blogger.com,1999:blog-10666456.post-77656520945091411122012-03-11T19:37:26.550-05:002012-03-11T19:37:26.550-05:00Brilliant!

With non-LIDE scanners you can't do direct imaging, and with tracing paper, ground glass, etc. you can sort of create a scanner camera.Dean W.

I rely on that and I add aperture stops as needed to extend the autoexposure range. The lens is f/8 and works in an inside office environment by itself; outside I need to drop to f/64 or f/128 or further.<BR/><BR/>The scanner light stays on in my camera. I've had a lot of problems with them if I disable the light, but having it on limits my sensitivity at the dark end. <A HREF="http://www.flickr.com/photos/mcgiffert/" REL="nofollow">Stephen Miller</A>, for instance, disabled his light and he has a fast lens that works really well in dimmer environments.Dean W.

My son and I came across you when researching his school photography project. I'd also just lashed together a black cardboard, 2 boxes sliding with a tracing paper screen, pin-ish hole 'camera obscura' ! It works fine but your camera is brilliant ! I just cannot quite understand how you get the exposure (& I've several old whole plate wooden cameras which I occasionally use). Is the scanner light disabled? Is it copying a tracing paper type focussed image ? I've certainly old reflective scanners I could take apart. Or are you just kidding ?! I hope not: I especially like the filing tray lens board..!<BR/>regards, Laurence BurnsBeachcoalhttps://www.blogger.com/profile/08558310025269404167noreply@blogger.comtag:blogger.com,1999:blog-10666456.post-4845442949306857332008-04-17T13:09:00.000-05:002008-04-17T13:09:00.000-05:00Come on, you've got a modern-tech device inside a ...Come on, you've got a modern-tech device inside a handsome wooden cabinet with a lens that was mainly in use during the late 19th century.
