Overview
 Scanning system for the National Gallery, London & The Uffizi Gallery, Florence. This was part of a European sponsored
project, with an aim to standardise information
gathered from the scanning of paintings in art
galleries.
Working
closely with specialists at the Uffizi Gallery,
Florence, LG Motion’s precision engineers
designed and built a digitising scanner to study
the gallery’s great paintings. The stepper
driven 3-axis scanner provides resolution down
to 10 microns and a scanning speed of
25mm/second. LG Motion used MiniTec’s modular
construction system to build this system, with
its 2 meter horizontal travel. A square ‘portal
frame’ carried a 2-axis scanning camera to
record a series of digitised images across the
surface of the painting, allowing images to be
digitally manipulated for analysis and study.
Objectives
A
system was required for precision scanning of
paintings to gather valuable information such as
colour change, detection of cracks, deformations
or imperfections.
Solution
The problem was solved
using a MiniTec aluminium component
structure, which allowed digital scanning
motion in X, Y and Z

-
A linear high precision
cross roller slide was used for focus
-
Fully motorised axis with
limits and datum sensors
-
Full 4 axis drives and
controls system with RS232 interface
Benefits Gained
- Standardised information
gathered from scanning the paintings
- Potential money saved
from early detection of colour alteration /
cracks / deformations
Products Used
- System 1 – Fabrication
- System 2 - Custom
designed MiniTec aluminium component
