An exemple of scanner

Postby santo » Wed Jun 10, 2009 2:07 pm


I address the bench of scannage to you which I assembled. It
comprises a red laser not focusable (of the shop DAVID) pulled by an
engine PAP of 84 steps and a reduction of 1/125ém. That thus gets a
minimum displacement of 125*84/360=29,16 per degrees, that is to say
for a sweeping of 30°, 875 lines, I work in 800*600 and that is thus
largely sufficient. The engine is controlled by a chart " Easy step "
the software is the version pro of DAVID, the computer is a centrino
1,6 GHz.

I you joint a certain number of photograph in order to better
apprehend the assembly. The pink small rule that one can see with the
top of the laser is used as reference at the time of the scan without
background. The parameters all of scan are with the green, except the
width beam which is yellow to 3,5.

By hoping that these indications can render service, cordial
