The 33rd ISOM (ISOM’23) will be held in a HYBRID style with both online and onsite meeting from Nov. 19 to Nov. 22, 2023 at the Takamatsu Symbol Tower, Kagawa, Japan.

On behalf of the ISOM organizing committee, I am delighted to welcome all of you to the ISOM’23.

The last ISOM meeting, held jointly with CLEO-PR2022 and ODF’22 in Sapporo, Japan, provided an opportunity to share the latest research results not only in the areas covered by ISOM, but also with researchers from a wide range of fields that have not previously participated in ISOM.

We believe that ISOM’s activities have been very fruitful and have produced significant results. Since the first ISOM in 1987, many papers have been presented and discussed in depth at the conference, which has led to new developments and new applications in the field of optical memory. It has not only produced innovations in optical memory technology, but has also led to the economic development of optical memory-related industries.

In 2017, ISOM extended the conference scope to broader optical fields 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 believe that the change of ISOM produces technological innovations and new applications in whole field related to this conference.

I sincerely ask all of ISOM’23 participants to discuss on new technologies of the next generation optical memory and new applications of optical memory technologies in coming ISOM’23.

The 33rd ISOM (ISOM'23) will be held from November 19 to 22 at TAKAMATSU SYMBOL TOWER, Takamatsu, Kagawa, Japan.

The origin of ISOM is SOM (Symposium on Optical Memory), which was held firstly in 1985 in Tokyo as a 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, and since 1995, ISOM has been held every year. The total number of papers of the past symposiums has reached 3,731, and the total number of participants has reached 10,812.

The purpose of the symposium was to provide a forum for information exchange on a broad range of topics covering science and technology in optical memory 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 in 2016. 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. Paper submissions related to the new scopes as well as the conventional ones would be strongly encouraged.

In ISOM'23, along this direction, it will be very much expected to discuss the current status of optical memory, imaging, sensing, and other related technologies. ISOM'20, and '21 were held online under COVID-19, and ISOM'22 was held hybrid style of onsite and online jointly with CLEO-PR2022 and ODF'22. ISOM'23 will be held with onsite and online presentations.

We are looking forward to your paper submission and seeing you in Takamatsu, Kagawa, Japan.


ISOM'23 will discuss the current status of Optical Memory, Imaging, Sensing, and Other Related Technologies.

The scope of ISOM'23 covers the above research fields. ISOM will provide the attractive fields to exchange the latest advances and/or ideas in the above research fields and also provide scientific interaction and collaboration.
