An electron microscope image is artistic and solves the
mysteries in science.
The electron microscope images were conventionally recorded
by films in an analogic manner. However, the machinery for
digitizing (e.g. an image scanner machine), which was
extended to the field of electron microscopy, was greatly
improved and has come into wide use in recent years. Once
electron microscope images are transformed into the
numerical data, a more detailed analysis can be performed,
and the useful functions of a computer such as saving,
filing and transmitting operations are utilized for them.
The development of new recording systems, such as the
imaging plate and the slow scan CCD camera, established the
new quantitative electron microscopy along with the
numerically observed images, instead of the previous
qualitative one. The digitized images are sure to be more
popularized in the future.
EMILIA (Electron Microscope Image LIbrary and Archives) is a
newly proposed system, which provides two principal services
on the electron microscope images as named "EM Gallery" and
"File Library". The efficiency of digitized electron
microscope images is to be studied by a group in Tohoku
University through the construction and utilization of
EMILIA, for which Prof.D.Shindo and Prof.K.Hiraga are
responsible.
The two major services of EMILIA are briefly introduced in
the following.
"EM Gallery" collects typical and exemplary high-resolution
electron microscope images on various subjects (dislocation,
interface and the structure of quasicrystals etc.). Most of
the images were observed by the groups of Prof.K.Hiraga and
Prof.D.Shindo in Tohoku University so far. The electron
microscope image, which is a guide to the world in atomic
scale, has been seen only in the scientific journals etc.
until now. EMILIA provides a more widespread opportunity for
the admiration of the electron microscope images, in which
digitized pictures of typical electron micrographs are
easily obtained by using the World Wide Web (WWW) service.
All the images in the "EM Gallery" are also listed in a
publication entitled "High-resolution Electron Microscopy
for Materials Science" (D.Shindo and K.Hiraga,
Springer-Verlag Tokyo(1998), ISBN 4-431-70234-2).
"File Library" is the archives for the digitized electron
microscope images. The digitized images are electronically
stored without a debasement in quality for a long time, and
the systematic filing results in an efficient use of the
database. A specific image is easily obtained from a vast
amount of data by using the file reference system. As
another application of "File Library", if there is a
personal computer beside electron microscope in the
laboratory, new specimen is observed along with a comparison
with the previous images stored in the "File Library". A
registration is required to use the service of the "File
Library".
