Successful Topical Meetings
world's experts in servo-control and interferometry met at
the ASPE Spring and Summer Topical Meetings. Both Meetings
were filled to capacity and both reported as being highly
Spring Topical Meeting in Boston, MA was the third in our
control series that started in Philadelphia in 2001. It began
with a well-attended tutorial on Sunday and a two day meeting
addressing control systems for such disparate precision applications
as Laser Interferometer Gravitational-Wave Observatory, atomic
force microscopes and scanning stages for VLSI systems. The
100 attendees listened to 28 papers supplemented by spirited
discussions of the problems and solutions.
Summer Topical Meeting in Asheville, NC was the fourth in
our Interferometry series that began in 1992. Distance, surface
profiling, optical coherence tomography and emerging technologies
were presented. Applications in research and manufacturing
for the optical, semiconductor, medical and scientific markets
were discussed and energetically debated during the sessions
and copious networking time. Participants left anticipating
the next meeting in 2015.
would like to thank the organizers and all who participated
in both meetings for making them a success.
next topical meeting will be jointly sponsored with euspen
in Charlotte, NC on the subject of Freeform Optics and Structured
Anniversary Annual Meeting in Atlanta , Georgia
momentum is building towards our Annual Meeting in Atlanta.
This is your once-a-year opportunity to find inspiration through
a host of technical presentations and poster sessions as well
as learn via our superb tutorial offerings, networking with
the experts and meeting with leading manufacturers. Click

manufacturing requires accurate, repeatable processes. Environmental
disturbances are major limiters to next generation manufacturing
strategies to improve machine/instrument resistance to environmental
disturbances are as follows:
Break all paths by which each disturbance influences performance.
Example: Shield all radiant, conductive and convective heat
Design for minimized response to disturbances. Example: Use
low thermal expansion materials to reduce thermal induced
Provide an appropriately controlled local environment. Example:
Temperature controlled rooms and environmental enclosures.
#2: Conceive an envelope encompassing the machine/instrument.
List the factors that are known to disturb the machine and
then weigh the magnitude of their influence. Formulate design
strategies to decouple, desensitize or control the effects
of these disturbances within the requirements of the machine/instrument
