        From the author of the January 1992 six-part EJASA (THE ELECTRONIC
    JOURNAL OF THE ASTRONOMICAL SOCIETY OF THE ATLANTIC) article (Vol. 3,
    No. 6A-6F) on Optical SETI (OSETI).  The following material, which has
    been slightly modified, was featured in the October 1992 issue of EJASA
    (Vol. 4, No. 3):


                 FIRST INTERNATIONAL CONFERENCE ON OPTICAL SETI

                            Dr. Stuart A. Kingsley

        As a result of the January EJASA article and floppy disk versions
    that I mailed to key members of the laser communications community, I
    was asked during the summer by Dr. David L. Begley of Ball Aerospace
    Systems Group, to organize a conference on Optical SETI for SPIE (The
    International Society of Optical Engineering).  Dr. David Begley is the
    previous chairman of the Free-Space Laser Communications conferences.
    
        The SETI conference was originally planned to be a single session in
    SPIE's Free-Space Laser Communication Technologies V conference, chaired
    by Dr. Stephen Mecherle of TRW, Inc.  Twelve months ago, I would not
    have believed that one year after publication of the EJASA article, we
    would be in the position to organize what is effectively, though
    unofficially, the First International Conference on Optical SETI.

        Let it be noted here that the word "optical" is used in a manner
    familiar to optoelectronics (photonics) engineers and scientists, as an
    umbrella term.  It denotes that part of the spectrum where optical]
    devices, e.g., lenses, are used for focussing electromagnetic energy.
    It is a superset of both "visible" and "infrared".  Astrophysicists are
    advised to adopt the more modern definition to avoid confusion in the
    scientific endeavor called Optical SETI.  Thus, the statement "optical
    and infrared SETI" is incorrect - rather it should be stated as "visible
    and infrared SETI".  The word "optical" is not to be taken as being
    synonymous with the word "visible", since the former covers all
    electromagnetic frequencies from the far-infrared to the ultra-violet.

        Even though the summer vacation period was a difficult time to
    organize a conference, I was able to get so many papers at short notice,
    that the single session was extended into a dedicated conference with
    three sessions and a separate published proceedings (approximately 200
    pages).  The latter will be available (hopefully) shortly after the
    conference and will constitute the first publication on this subject.
    The OSETI conference follows on immediately after the Free-Space Laser
    Communication Technologies V conference.

        This SETI event will be of particular interest to laser
    communications scientists and engineers.  It presents the opportunity to
    help resolve the dichotomy within NASA that while lasers are fine for
    GEO to GEO, GEO to LEO, deep-space and interstellar communications, ETIs
    would not use such technology to signal emerging technical civilizations
    (us).  The first session has been devised to bring the laser
    communications community up to speed on Microwave (Conventional) SETI
    (MSETI) and general SETI related matters.  The second and third sessions
    are specifically devoted to Optical SETI topics.  Since I thought it
    important to get a variety of opinions as to the veracity of SETI and
    the efficacy of the optical approach, I have included many shades of
    opinion.

        We are fortunate in being able to have Arthur C. Clarke kick off
    this conference from his home in Sri Lanka.  We are working to set up a
    live international satellite link with Arthur C. Clarke but at a minimum
    we will have a video-taped address.  These days, Clarke's health
    precludes extensive travelling.  We are also investigating the
    possibility that NASA Select TV could cover the entire conference on a
    live or taped-delayed basis.  If you cannot attend this conference but
    would like to see it transmitted by NASA Select, write to SPIE and NASA
    Headquarters requesting this coverage.  The more people lobby for this
    the more likely we will get the cooperation of the concerned parties.
    For those with a TVRO (TeleVision Receive Only) satellite dish, NASA
    Select TV is available on Satcom F2R (72 W), Transponder 13.  Look out
    for coverage of the HRMS switch-on on NASA Select TV tomorrow
    (October 12).

        The "Grand Old Man" of SETI, Dr. Bernard M. Oliver, who is extremely
    critical of the optical approach, will demonstrate for the first time to
    the laser communications community why ETIs would not use lasers for
    (SETI) interstellar communications.  We also have Professor Frank
    Tipler, a strong critic of SETI, explaining why both Microwave and
    Optical SETI is a waste of time since he thinks that we are the first
    civilization in this galaxy.  Noted philosopher, Professor Neil Tennant,
    will present his ideas as to why there could be major problems in
    actually decoding the message on an ETI signal.  There will be a
    discussion roundtable at the end of the conference, moderated by Nobel
    laureate Charles Townes (1964 - masers/lasers), who earlier will be
    talking about his Carbon Dioxide (CO2) Optical SETI laser work, and the
    CO2 OSETI observations presently being conducted by Dr. Albert Betz on
    Mt. Wilson.

        Note, that as with previous SETI publications, the latest SETI book
    by Frank Drake and Dava Sobel "Is Anyone Out There?" hardly mentions the
    optical approach.  This conference intends to redress that omission.
    This "controversial" OSETI conference should be a "fun" event but you
    don't need to be a laser communications engineer or SETI scientist to
    attend - just a curiosity about "our" place in the grand scheme of
    things.

        You are encouraged to remail this material to anyone you know with
    interests in SETI.  You might like to print out the program below and
    pin it up on your astronomical society, company, faculty, or school
    notice board.

    *Rate for a three-day conference.

    **There is no separate registration rate for the SETI conference.

        Attendees for the SETI conference will have to pay for two days.  If
    you can spare the time, attendees are recommended to take in the
    Wednesday morning and afternoon, and Thursday morning sessions of the
    Free-Space Laser Communication Technologies V conference, as this
    technology is very relevant to Optical SETI.  The cost for the full
    conference period (three days) is little more than for the two day OSETI
    conference alone.


    SPIE Proceedings Volume 1867              $ 35

        These proceedings will also include a copy of Dr. Lesh's large
    review paper on NASA's optical communications activities, which is to be
    presented at the Free-Space Laser Communication Technologies V
    conference.

        NOTE:

        Articles on SETI have appeared in recent magazine publications,
    which include the September issue of LIFE magazine, the October issue
    of ASTRONOMY, and the November/December issue of SMITHSONIAN AIR &
    SPACE.  See also recent issues of TIME and NEWSWEEK.  The November
    issue of SKY & TELESCOPE has a long article by Robert Naeye about
    Microwave SETI, and mentions the optical approach.  This is the first
    published popular account of OSETI in the printed media.

        This month, in celebration of the Quincentennial of Columbus'
    discovery of the Americas and the official start of NASA's Microwave
    Observing Project (MOP), now renamed the High Resolution Microwave
    Survey (HRMS), I have begun the construction of what is believed to be
    the world's first Amateur Optical SETI (AMOSETI) Observatory.  This will
    be based around a Schmidt-Cassegrain telescope of about 10-inch
    aperture.  The telescope will probably be the new Meade LX200, as it is
    one of the most advanced on the market today for use under computer and
    CCD control.  Thus, Columbus Day (October 12) not only sees the official
    start for the most detailed Microwave SETI activity to date, but also
    the start of Amateur Optical SETI.

        In the last paper of the conference, I will be reporting on the
    amateur approach to Optical SETI and any work done to date on my
    observatory system.  EJASA will from time to time carry progress reports
    on this activity and the outcome of the conference.  As I indicated in
    last January's EJASA Optical SETI article, it is my intention that
    AMOSETI will become a world-wide activity for amateur astronomy groups
    and societies.  In the January 1993 issue of EJASA, there will an
    addendum to last January's EJASA article, including updated conference
    program information.

        This week, SPIE is mailing the full OE/LASE '93 program.  Please
    note the new dedicated fax number for Fiberdyne Optoelectronics.  I look
    forward to meeting with you in Los Angeles in January.
