Pi : (Pinkney raised a point here that dealt with the rate of acqui-
sition of information. This was included in Item 8.)
Badekas: With regard to Dr. Ghosh's suggestion, I find that there is some
difficulty, because to me photography with a time distribution does not
change its nature. It is still conventional. If we accept such an approach
then every time a photography is repeated it would become non-conventional.
Ghosh: We may call this "non-conventional" application of "conventional"
photography, or conventional space photography and the like would come
under such categories also.
Linkwitz: Accuracy would also be an aspect to discriminate between con-
ventional and non-conventional imaging. On the left side conventional
accuracy is determined by the resolving power of the optical system, and
the resolving power of the film. And on the other side, non-conventional
imaging accuracy is determined by the wavelength. (Item 9)
Gates: Yes, that is a very important point. And I am sure there are
others we haven't talked about. But since time is getting on I must come
now to the last point that I want to make. We would like to set up a
working group of people who feel they would like to join in further dis-
cussion of the subjects we should put forward for special consideration at
the next congress.
(Further discussion was held during lunch. The discussion dealt
with a choice of possible people to whom the Working Group felt
that invitations should be sent, to give invited papers at the
1980 Congress in Hamburg. )
Gates closed the session by thanking the speakers.
