Welcome and Introductions
S. VanKerkhove was unable to attend so D. Aikens opened the meeting at 8:48 a.m.
Adoption of Agenda
H. Johnson moved that the draft agenda be approved, M. Dowell with additions
Approval of the Sunday, August 26 ASC OP Meeting Draft Minutes
G. Boultbee noted that "US" had to be added to the minutes in the line, "D. Aikens, G. Kohlenberg, A. Krisiloff and R. Williams
represented the
US
at the June ISO/TC 172/SC 1 meeting in Paris." G. Boultbee moved that the edited draft minutes be approved.
R. Williamson seconded the motion; the motion passed unanimously.
Reports
Performance Based Optical Surface Imperfection Standard
G. Boultbee reported that BSR/OEOSC OP1.002 is ready for Task Force balloting. Assuming that the Task Force ballot
is successful, then the entire ASC OP will be balloted for final approval. D. Aikens asked how many positive votes were
required to approve the draft. The Secretary said that a simple majority of the participants of the Task Force and then ASC
OP can approve the document. D. Aikens asked what constituted the majority. The Secretary replied that all participants on
the Task Force and all participants on ASC OP determine the two majority figures.
The result of the balloting process will determine whether a TF 2 meeting will be necessary in August.
G. Boultbee said that Northrop Grumman was preparing a report concerning their evaluation of the scratch and dig
imperfection measuring process for the August SPIE meeting.

Wavefront Specification Project
A. Krisiloff summarized the meeting. The Task Force reviewed P. Takacs early draft of BSR/OEOSC OP1.004. There
was a discussion concerning the definition of the two-dimensional power spectral density. P. Takacs will continue
development to point where he has a handle on definitions and notation. S. VanKerkhove and P. Takacs will have an interim
teleconference to organize the two drafts. S. VanKerkhove introduced his outline for BSR/OEOSC OP1.005.
Status of Action Items
Single-letter mnemonics concern. G. Boultbee reminded the group that there was a concern that ISO had changed the indication
for MTF to a single letter. The committee had asked D. Aikens to write a letter to ANSI to protest this change to the MTF standard.
D. Aikens reviewed traditional optics books. He found that an overwhelming majority of books define MTF and then list a function
name as one letter such as M for the equation. The authors refer to the variables as MTF, but use single letter for functional notation.
He chose not to write a letter to ANSI. The standards do have to be rewritten to use a single letter in equations, but can still continue
using MTF as the mnemonic. The Secretary asked if D. Aikens had reported his findings to the British delegation. He replied that he
had not, as yet, done that; but he did e-mail the ISO subcommittee chairperson.
Press release for ISO 10110 adoption. D. Aikens with M. Dowell will write the press release for Secretary to release. The
Secretary said that he would put it on the News page of the optstd web site, send it to OSA, SPIE, and Photonics Spectra. M. Dowell
said it could also be submitted to NCSOI.
The committee asked Secretary to create a prominent listing of Action Items in minutes, etc. M. Dowell said that some groups use
a table of action items at the end of minutes. G. Boultbee suggested a protected Action Item list on the web for TF viewing. If it is not
too much additional work, a spreadsheet with all of the to-do items for each committee, task force and the board would be useful.
ISO Standards Development Projects
Adoption of ISO 10110-1 and 10 as an American National Standard
D. Aikens had not formed a TF to do this because he had to develop the class, but he now knows how to group the
individual sections. He proposes making ISO 10110 1 and 10 as one national standard with a foreword stating that it is an
American National Standard. Although there may be references to sections not yet adopted as US standards, other US
standards can be substituted as references. Standards are modular but there is a rats nest of normative references which
require the user to accept all of them. If ASC OP does not want to adopt Part 7, for example, then references to it must be
removed.
L. Endelman suggested that D. Aikens tabulate his concerns about the current documents for all to review. M. Dowell
suggested that he review it at a future meeting.
C. Gaugh asked if the TF should be approaching the drafting software houses, such as Autodesk, Solidworks, or Pro/Engineer,
about this subject. D. Aikens said that he was not familiar with those packages, but that it is a good idea.
M. Dowell suggested that
ASC OP determine if there are any Gold Partners for one of these software houses. A. Krisiloff volunteered to make this contact.
D. Aikens has volunteered to draft the ISO NWP version that will be examined in Bucharest.
ISO 10110-6-1996 lacks ability to call out a total indicated run out.
This is a perfect opportunity to have a US sponsored
ISO 10110-6 NWIP using TIR for tilt. R. Williamson agreed to accept this task. W. Czajkowski will help him.
Maintaining Membership List
The Secretary reminded the committee that ANSI requires that he maintain an ASC OP membership list by year. He presented the
list of 23 distinct organization members and asked if any one is missing. D. Aikens asked if representatives from SPIE and OSA have
voting rights. The Secretary confirmed that they do. L. Endelman is the SPIE representative and J. Oberheuser was the OSA
representative.
M. Dowell asked what happens now that she represents two organizations. The Secretary replied that she will have two votes.
The Secretary also presented a list of participants by name, indicating the primary and alternate status of each.
C. Gaugh noted that he was not listed as being registered to attend the meeting. The Secretary said that the list was created on
Wednesday before the meeting, and he left for California on Thursday. Any e-mail replies to him after Wednesday would not be
reflected in the list. He went on to say that he creates unique subjects for the e-mail meeting notices and asks the attendees to reply to
that e-mail so that he can search incoming e-mails by that title to collect attendance information. If a person replies only once saying
that he or she will be attending all meetings, then the Secretary would have to go through all of the incoming e-mails to collect
attendance confirmations. W. Czajkowski said that he was getting replies from other participants confirming their participation to
meetings. The Secretary reminded the group to hit Reply not Reply All.
The Secretary also reported that there are several participants whose organizations have not paid in a couple of years. He will
report this at the Board meeting and suggest that if the fees are not brought up to date within a few weeks that he will change those
organizations to observer status.

Other Business
W. Czajkowski asked for a new list of passwords.
The secretary said that the pass words have not changed and asked each person
to have the browser remember the password. M. Dowell said that does not work for her because her computer management
organization deletes such passwords each month.
A. Krisiloff said that he created a list of the Task Force structure as he understands it. He asked if this were the appropriate time to
discuss it. The Secretary said that the starting time for the Board meeting was rapidly approaching. L. Endelman suggested that
A. Krisiloff send his list to the Secretary for distribution.
Time and Place for Next OP Meeting
A. Krisiloff moved that the OP meeting be held in Rochester, NY in October. M. Dowell seconded the motion, which carried.
Adjourn
Since there was no further business to come before the committee, H. Johnson moved that the meeting be adjourned. M. Dowell
seconded the motion. The meeting was adjourned at 10:07 a.m.
