3D digitising systems based on the
principle of fringe projection play an
important role in industrial metrology.
However, conventional fringe
projection systems meet their limits
when it comes to scanning reflective or
transparent surfaces. In these cases
the measuring object can only be
digitised by preparing the surface, ie
with a spray.
To overcome this problem, the German
company AiMESS has developed a
fringe projection system that makes
surface preparation unnecessary.
In contrast to other fringe projection
systems, the R3Dscan does not
analyse an object’s reflection. Instead,
it makes use of an infrared detector for
tracing the energy that is absorbed by
the measurement object and
converted into heat.
As the nature of the surface finish does
not affect this patented infrared
measurement method, the R3Dscan
allows for instant scanning of
reflective, dark or transparent surfaces.
Not only spraying is avoided when
applying the R3Dscan: the
time-consuming procedure of placing
markers on the measurement object is
not necessary either.
Thanks to a highly precise way of
positioning, the single views of a
measuring object are automatically
matched to a complete data set.
Furthermore, the R3Dscan is
insensitive to ambient light. No matter
how light conditions may be, the
system will always deliver accurate
measuring results.
As the system allows for
measurements without prior spraying,
the infrared scanner opens completely
new application areas in
manufacturing.
As an example, it is possible to use the
system in-line for measuring objects in
step with the production cycle.
Moreover, the R3Dscan is suitable for
all applications in which neat cleaning
of the measuring object cannot be
guaranteed after spraying.
The complete system has a weight of
around 25kg and works with a 220V
power supply. One shot covers a
measuring volume of 250x250x100mm³.
Larger scans can be realised by
relocating the scanner or the object to
be measured.
Furthermore, thanks to the modular
configuration of the system, it is
possible to connect several projectors
to one single computer. Thus, no
matter how large the measuring object
may be, it only takes one shot to
acquire the whole part. The result “OK”
vs “not OK” is computed within
seconds.

New latching Micro-D™ and BiLobe®
connectors from Omnetics Connector
Corporation use a squeeze-latch
system to make quick cable
connections to mating connectors and
panel equipment.
The small, lightweight connectors are
available at both 25 and 50
one-thousands of an inch spacing, and
have passed extensive shock and
vibration testing including pull testing
exceeding 100lb pull force.
The connectors are designed to be
used in rugged applications such as
unmanned vehicles, optical
surveillance, and flight deck test
equipment, where quick connect and
disconnect methods are not readily
available in a rectangular connection
system, and in medical devices, such
as surgery tools, ultrasound monitors,
and imaging scopes that require
frequent connection and removal from
instrument panels.
Omnetics uses a nickel/gold plated
one-piece beryllium copper flex pin
design, operable at temperatures
between –55ºC and +125ºC. Wired
connectors include 26 AWG Teflon®
insulated copper wire that provides up
to 3 amps per line on micro sizes, and
30 and 32 AWG wiring for nano-sized
connectors.
A wide range of wire count and cables
can be designed into custom
back-shells. Cable systems include
braided shields to reduce electrical
noise interference (EMI) and crosstalk.
