WELCOME TO ISOM’24
WELCOME STATEMENT FROMTHE ORGANIZING COMMITTEECHAIRPERSON
The 34th ISOM (ISOM’24) will be heldfrom Oct. 20 to Oct. 23, 2024 at the Arcrea
HIMEJI in Himeji, Hyogo, Japan.
On behalf of the ISOM organizing
committee, I am delighted to welcome allof you to the ISOM’24.
The last ISOM meeting, held in Takamatsu City, Kagawa
Prefecture, attracted the largest number of participants andpresenters in the past 10 years. Last year's meeting was also a faceto-face meeting, which led to lively discussions and a deepening offriendships among the participants.
We believe that ISOM’s activities have been very fruitful and haveproduced 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 thefield 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 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 andnew applications in whole field related to this conference.
I sincerely ask all of ISOM’24 participants to discuss on newtechnologies of the next generation optical memory and new
applications of optical memory technologies in coming ISOM’24.

Tsutomu Shimura
ISOM’24 Organizing Committee, Chairperson

INTRODUCTION
The 34th ISOM (ISOM’24) will be held from Oct. 20 to Oct.
23, 2024 at Himeji.
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 3,823, and the total number of participants hasreached 10,943.
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 continuously updated and have beenreorganized in 2016. To further highlight them, the officialname 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’24, 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,lots of papers have been submitted more than usual in thisISOM.
As the COVID-19 pandemic has calmed down, we are now
able to hold face-to-face events. Therefore, this ISOM will beheld as a face-to-face event, in principle, with the exceptionof some invited speakers, but we will adopt a hybrid stylewhere participants can attend online. We appreciate yourparticipation as presenters and audience, and we are looking
forward to seeing you at HYBRID style meeting in Himeji.

Tokyo Polytechnic University (Japan)
I introduce the background of the invention of
the phase-shifting mask. Simultaneously, I
examined the imaging theory, leading to theconsistent scalar imaging theory. In lithography,
object and image fidelity is not necessary, but
exposure margin and depth of focus are required.
I discuss from this perspective.

Light-in-flight holography is an ultrafast imaging
technique that can reconstruct the evolving
wavefield of light, encoding 3D data at
femtosecond resolutions. Existing algorithms formodelling those are computationally intensive

Digital holographic imaging provides access tothe optical phase information. However, theintensity-only response of commercial imaging

devices leads to ill-posedness of thereconstruction problem. Here, we introduce a
general algorithmic framework based on

Specifically, we exploited various signal priors of

Tu-E-10Adaptive Reed-Solomon Decoder for HighDensity Optical Storage

Danyang Li, Diqing Hu, Ke Shi, Yang Liu
Huazhong University of Science and Technology(P.R.China)
In the era of rapid digitization, the challenges
posed by the storage of vast quantities of cold
data are driving the pursuit of higher storage
densities in optical storage technology. However,increased storage density exacerbates the issuesof inter-code and inter-channel crosstalk, leading
to higher data bit error rates (BER), which
complicates data error correction. Optical disk
systems typically depend on Reed-Solomon (RS)codes for data error correction, thus demanding
further analysis and design of RS decoding
methods to meet the demands of high-density
optical disk systems.To address the challenges,
this paper introduces an RS decoding strategy
that combines soft/hard decision decoding basedon signal stream analyzing and splitting. This
strategy utilizes the Maximum Likelihood
Sequence Error Estimation (MLSE) to evaluate
the signal quality and divides the signal flow intohigh BER stream and low BER stream. A harddecision decoding algorithm with higher
efficiency decodes the low BER stream, and asoft decision decoding algorithm with superior
error correction decodes the high BER stream.
Therefore, this strategy promises enhanced
decoding efficiency and robust error correction
capabilities.

Two advanced imaging technologies arepresented that visualize objects disturbed throughscattering and turbulent media. The first
technology is high-speed 3D imaging behindheterogeneous composite media using a
Functionally Integrated Waveguide Illuminatorbased on common-path digital holography. The
second technology is single pixel imaging using
deep learning reconstruction to suppress
atmospheric turbulence.

Jinan University (P.R.China)
We report a single-pixel computational opticalimaging technique that can see through flames.
Flames can be computationally muted in theimages recovered through structured illuminationand the associated image recovery algorithm.
Consequently, an optical fire “distinguisher” isachieved. The reported technique operates at thevisible waveband and can see a dynamic scenethrough flames at the video frame rate in realtime.
