WELCOME TO ISOM’21
WELCOME STATEMENT FROMTHE ORGANIZING COMMITTEECHAIRPERSON
We decided to hold the 31st ISOM
(ISOM’21) in a considerably different
style from the original plan, in response to
the spread of COVID-19 infections. The

ONLINE conference will be heldfrom Oct. 3 to Oct. 6, 2021 without holding on-site meetingat the Kobe Chamber of Commerce and Industry, Kobe, Japan.
On behalf of the ISOM organizing committee, I am delighted towelcome all of you to the ISOM’21.
The last ISOM meeting held online, was successful to share newdevelopments of holographic memories, digital holography,
computational imaging, bio-sensing, display, nanophotonics andplasmonics, etc.
In 2017, ISOM extended the conference scope to broader opticalfields and applications, and changed the conference name as“International Symposium on Imaging, Sensing, and Optical
Memory.” The new ISOM includes the fields of image sensing,
medical and bio-optics, nano photonics, information system,
holographic technologies, as well as optical memory. We believethat the change of ISOM produces technological innovations inimaging and sensing technologies, and many applications of
optical memory technologies in the fields of medical and biotechnologies, 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 optical industry.
I sincerely ask all of ISOM’21 participants to discuss on newtechnologies of the next generation optical memory and new
applications of optical memory technologies in coming ISOM’21.

Tsutomu Shimura
ISOM’21 Organizing Committee, Chairperson-4-INTRODUCTION
The 31st ISOM (ISOM’21) will be held ONLINEONLY due to the COVID-19 pandemic, from Oct. 3
to Oct. 6, 2021 WITHOUT the on-site meeting at the
Kobe Chamber of Commerce and Industry, Hyogo,
Kobe, Japan.
The origin of ISOM is SOM (Symposium on Optical
Memory), which was held firstly in 1985 in Tokyo asa Japanese domestic symposium. The first ISOM
(International Symposium on Optical Memory) was
held in 1987 also in Tokyo. Until 1994, ISOM and
SOM were held alternately every other year, andsince 1995, ISOM has been held every year. The total
number of papers of the past symposiums hasreached 3,595, and the total number of participants
has reached 10,626.
The purpose of the symposium was to provide aforum for information exchange on a broad range of
topics covering science and technology in opticalmemory and its related fields. However, information
explosion in the internet and cloud 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, the scopes of ISOM are being
continuously updated and have been reorganized in2016. To further highlight them, the official 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’21, along this direction, it will be very much
expected to discuss the current status of opticalmemory, imaging, sensing, and other related
technologies. In addition, lots of papers have been
submitted more than usual in this ISOM.
We appreciate your participation as presenters andaudience, and we are looking forward to seeing you at
online meeting.
