International scope and collaboration

Symposium chair Professor Takashige Omatsu of Chiba University welcomed the audience to the two-day SPIE-OSJ Biophotonics Japan at the University of Tsukuba Tokyo Campus on Tuesday 27 October.

Omatsu provided some background on the origin of the jointly sponsored symposium, observing that 2015 is the International Year of Light and also the year that the Optical Society of Japan (OSJ) became independent of the Japan Society of Applied Optics. SPIE President this year is Toyohiko Yatagai of Utsunomiya University, and it is SPIE's 60th birthday.

The OSJ was founded in 1952 and currently has 600 members and 200 student members, Omatsu noted. He talked about SPIE's international reach and connection to industry, and invited the audience to consider joining SPIE and work together on future collaborative activities.


Early-stage cancer detection

Omatsu introduced the plenary speakers, starting with Jennifer Kehlet Barton, professor of Biomedical Engineering and Associate Vice President for Research at the University of Arizona and a member of the SPIE Board of Directors.

Barton spoke on optical imaging techniques for early-stage cancer detection. After providing an overview of imaging processes, she discussed recent advances in miniature endoscope design for optical coherence tomography, fluorescence spectroscopy, and multi-photon imaging.

Barton provided details of her most recent work, designing and testing an OCT fluorescence imaging endoscope for use in imaging the fallopian tubes.


Interferometric and spectral imaging

In the second plenary talk, SPIE Fellow and 2015 Dennis Gabor Award recipient Professor Kazuyoshi Itoh of Osaka University covered the background of various imaging and interferometric techniques with applications ranging from imaging in outer space to living cells.

Itoh reviewed radio wave interferometers that are not impacted by atmospheric interference owing to the long wavelength and showed how these can also be used to generate spectral information from multi spectral imaging radio interferometers.

At optical wavelengths air turbulence is severe. However Fourier transform spectral imaging offers improved performance and capabilities. Itoh reviewed this technique and discussed the principle of the new Space Infrared Interferometric Telescope (SPIRIT) which is a pathfinder for Submillimeter Probe of the Evolution of Cosmic Structure (SPECS). This concept is based on Fourier transform spectral imaging or double Fourier technique.

Itoh discussed the technique and advantages of stimulated Raman spectral spectroscopy and provided a specific example of high-speed spectral imaging system developed by Yasuyuki Ozeki of the University of Tokyo, et al. (reported on later in the morning by Professor Ozeki in paper 9792-2).

Professor Itoh concluded with a discussion of the application of these techniques to animal imaging and the signal processing required to deal with the large amount of data.

Poster session discussions

A well-attended poster session after lunch on Tuesday afternoon saw stimulating discussion among conference attendees. Highlights of the meeting as noted by several of the participants included the quality of presentations, excellent networking, and high level of engagement by the audience.

Multiscale optical imaging

Kristen MaitlandIn an afternoon session on Microscopic Imaging, SPIE Board of Directors member Professor Kristen Maitland of Texas A&M University spoke on multiscale optical imaging of epithelial tissue with FLIM (fluorescence lifetime imaging) and reflectance confocal microscopy (9792-9).

Mailtland described techniques she and her team are pursuing, with a particular focus on the development of a new noninvasive instrument for cancer detection. The goal is to improve identification of neoplasia and dysplasia in oral mucosa, by detecting metabolic and structural changes in the tissue and evaluating cellular changes in the epithelium.


Welcome -- and a surprise

Attendees enjoyed traditional Japanese dishes as well as international cuisine in the evening welcome reception.

In welcome remarks, organizers once again noted the high quality of the talks, excellent level of interactions, and the highly international nature of the attendees, with nearly half of attendees from outside Japan.

SPIE President Professor Yatagai said he thought the meeting was highly successful and hoped attendees would participate in future meetings. Professor D. P. Tsai of the Academia Sinica of Taiwan extended his greetings and commented on the extensive investment going into biophotonics in his country as well as other regions of Asia (Professors Yatagai and Tsai, at left above).

"The first SPIE-OSJ Biophotonics meeting has been a major success and exceeded our expectations," said Dr. Andrew Brown, SPIE Senior Director at the end of the first day, echoing other comments about the quality of the presentations, high level of engagement, and the international nature of the audience -- "truly an international event."
