WELCOME TO ISOM’19
WELCOME STATEMENTFROM THE ORGANIZINGCOMMITTEE CHAIRPERSONThe 29th ISOM (ISOM’19) will be heldin Niigata, Japan from Oct. 20 to 23,
2019.
On behalf of the ISOM organizing committee, I am delighted
to welcome all of you to the ISOM’19 in Japan.
The last ISOM meeting held in Kitakyushu, Japan was very
successful to share new developments of holographic
memories, digital holography, computational imaging, biosensing, display, nanophotonics and plasmonics, etc.
Two years ago, ISOM extended the conference scope tobroader optical fields and applications, and changed theconference name as “International Symposium on Imaging,Sensing, and Optical Memory.” The new ISOM includes thefields of image sensing, medical and bio-optics, nanophotonics, information system, holographic technologies, aswell as optical memory. We believe that the change of ISOM
produces technological innovations in imaging and sensing
technologies, and many applications of optical memory
technologies in the fields of medical and bio-technologies,
image sensing, nanotechnologies, etc.
We are very proud of the ISOM activities, because many oftechnologies leading new developments and new applications
have been first presented and discussed in ISOM meeting.
Since the first ISOM meeting in 1987, ISOM has led
innovation of optical memory and economic growth in opticalindustry.
I sincerely ask all of ISOM’19 participants to discuss on newtechnologies of the next generation optical memory and new
applications of optical memory technologies in coming
ISOM’19.

INTRODUCTION
The 29th ISOM (ISOM’19) will be held from October 20 to
October 23, 2019 at TOKI MESSE, Niigata, Japan.
The origin of ISOM is SOM (Symposium on Optical
Memory), which was held firstly in 1985 in Tokyo as aJapanese domestic symposium. The first ISOM (International
Symposium on Optical Memory) was held in 1987 also inTokyo. Until 1994, ISOM and SOM were held alternately
every other year, and since 1995, ISOM has been held every
year. The total number of papers of the past symposiums hasreached 3,440, and the total number of participants hasreached 10,410.
The purpose of the symposium was to provide a forum for
information exchange on a broad range of topics coveringscience and technology in optical memory and its related
fields. However, information explosion in the internet andcloud service has been enforcing optical memory to change
from that for consumer storage to that for enterprise storage.
Many colleagues of us have been seeking for new frontiers of
optical memory technologies. Considering this situation, thescopes of ISOM are being continuously updated and havebeen reorganized in 2016. To further highlight them, theofficial name of ISOM was changed from “International
Symposium on Optical Memory” to “International
Symposium on Imaging, Sensing, and Optical Memory” in
2017. Presentations related to the new scopes as well as theconventional ones would be strongly encouraged.
In ISOM’19, along this direction, it will be very much
expected to discuss the current status of optical memory,
imaging, sensing, and other related technologies. In addition,
we are planning to have a demonstration session at the
symposium as in the last four years, in which authors will beable to show their vivid and attractive research results.
We are looking forward to your paper submission and seeing
you in Niigata, Japan.

To increase the recording density of computergenerated-hologram-based holographic data storage,
phase signals are utilized through the Fourier
