Optical Technology and Measurement for Industrial
Applications 2021 OPTM 2021

Conference Co-Chair

Takeshi Hatsuzawa

This is the third conference of OPTM (Optical Technology and Measurement for Industrial Applications
Conference) since 2019. More than 50 presentations including oral and poster in 2019, and 20 oral and 15
poster presentation in 2020 have been presented. Although conference restrictions are increasing due to thespread of COVIDF-19, it looks like the OPTM activity has taken root among researchers.
The aim of the OPTM 2021 is to provide an international opportunity for introducing up-to-datetechnology in the filed of optical measurement and their applications for industries, at the same time, providing a networking opportunity
among young researchers and students is another important role of the conference. Also in the venue, other optics related exhibitions
and conferences will be hold, which will be a good chance to foster interest in different technical fields. We hope your visit to port ofYokohama will be a nice experience in your technical and research carrier.

It is really a pleasure to me to welcome you to the third Conference of Optical Technology andMeasurement for Industrial Applications. This year again the program committee was able to arrange a setof presentations that give an insight into various fields of optical metrology, covering topics from theoreticalsimulation to industrial applications. In these hard times of limited access to laboratories and travel
restrictions this is not a matter of course and I want to express my appreciation to the members of theprogram committee and special thanks to the program committee chair, Professor Yukitoshi Otani. The young OPTM conference series
is on a good way to become a cornerstone event for the scientific community in optical metrology.
Though I am happy that today´s information technology makes it possible to attend this conference even without being able totravel, it makes me sad that we do not have the opportunity to meet physically. International personal contacts are essential for theprogress of science. The annual OPIC conference and trade fair event at Yokohama is an excellent setting for meeting international
colleagues. I wish OPIC a flourishing future in the following years.
Even if you are not able to visit Yokohama this year I wish all of you a pleasant OPTM conference. I am sure that for everybody there
is some new information to find and maybe you get aware of a colleague whom you did not know before.
Enjoy the conference and hopefully we will meet again next year at Yokohama!

We are delighted to have the 3rd conference on Optical Technology and Measurement for Industrial
Applications (OPTM) as part of OPIC 2021. These years we have been forced to persevere through difficult
times caused by natural (and human-made) disaster, and especially coronavirus pandemic.
This conference has potentially its origin in SPIE meetings and relates in any way to another concept
optomechatronics that was originally born in Japan.
Conventionally research is apt to be evaluated higher from the theoretical or analytical viewpoint.
However, in addition to theoretical or analytical result, research should be also assessed from practical utility. Industrial-applicationconscious research as well as fundamental research should be attracted more attention.
In the near future, after we succeed in overcoming problems, we expect truly useful and excellent result will be realized from theacademic and practical viewpoint.
Let’s enjoy this meeting and produce new result by exchanging opinions.
