13 members left (6 of them finished PhD studies) and 8 members joined the chapter.

Chapter activities The organization of 7th International Young Scientist Conference “Developments in Optics

and Communications 2011” (DOC 2011) April 28-30 in Riga. More than 50 participants from

six countries. More information - http://www.osa-latvia.lv/doc/

Student chapter leadership workshop was organized during DOC 2011. Leaders from Univ. of

Latvia SPIE Student Chapter, Taras Shevchenko National Univ. of Kyiv SPIE Student Chapter

and Univ. of Latvia OSA Student Chapter shared their experiences on the management of

student chapters. Representatives of future Vilnius Univ. SPIE Student Chapter also attended

the meeting.

SPIE Education Outreach Grant 2011 - to help establish optics and photonics research

center. In spring 2011 SPIE Student Chapter of University of Latvia received the SPIE

Education Outreach Grant. The Grant was spent to purchase equipment for Optics and

photonics outreach center for students in the heart of Riga, Institute of Atomic physics and

Spectroscopy at University of Latvia. The idea of the center is to popularize science and

optics and photonics as an imprescriptible part of it among students in Latvia with an aim to

encourage them to choose studies in the field of science in the future. Hands-on

experiments are widely used in the center. Below one can observe photos of activities in

optics and photonics outreach centre.

Several members were involved in the organization of international scientific conference

Functional Materials and Nanotechnologies 2011. More information -

http://www.fmnt.lu.lv/

Members of chapter participated in “Science Night 2011” events on September 23.

Participation in organizing School for Young Physicists where students and teachers of

Faculty of Physics and Mathematics, University of Latvia, teach and show interesting Physics

experiments to scholars from secondary schools of Latvia

Members of the chapter organized lectures at their institutions for school students

presenting their scientific work and laboratories and motivating youngsters to choose

studies in physics.

President of the chapter Dainis Jakovels attended conference “SPIE Optics + Photonics 2011”

and participated in Student Chapter Leadership Workshop. Later, he shared experience

giving talks at the seminar of Institute of Atomic Physics and Spectroscopy and ULSPIE

Student Chapter meeting.

Inga Saknite participated at 61st Meeting of Nobel Laureates in Lindau which is a yearly event

where only a selected amount of young researchers (mostly, PhD or Master students) are

invited and meet with 25 Nobel Laureates.

Inga Saknite participated at Physics Summer School in Ljubljana, Slovenia, presenting her

research regarding optical properties of skin, as well as exchanging experiences with

researchers in the field of Medical Physics at University of Ljubljana.

8 new members joined the chapter – Inesa Ferulova, Raitis Grzibovskis, Sandis Spolītis, Andis

Supe, Aleksejs Udalcovs, Eriks Zaharans, Janis Zaharans and Elmars Zarins.

Our grants and awards 23 members received Europen Social Fund scholarship.

Inga Saknite received a grant to study Biomedical Engineering at Linköping University,

Sweden, as an exchange student (programme ERASMUS).

Lasma Asare - ThorLabs award for the Best Student Paper from a Developing Country.

Scientific activities of chapter members Scientific activities of chapter members cover such disciplines as atomic and molecular

spectroscopy, optical materials, vision science, bio-photonics, communications and non-

linear optics. Some examples of scientific activities are listed below:

- Development of novel organic materials and waveguides for nonlinear optical

applications so as the techniques for thin film linear and nolinear optical

characterization. The main goal is to develop a low optical loss and halfwave voltage

organic waveguide electro optical modulator with a several gigahertz bandwidth.

- Optical recording in light sensitive materials

- Eye optical system quality and image quality assessment.

4

- Study of the availability of different color print technologies (three layer

photographic process, tint printing) for creation of color vision test plates, for an

accurate diagnosis and grading of color vision anomaly.

- Color vision testing (tests and matching). Illumination and colorimetry, color

reproduction, color appearance. Eye aberrations and vision, contactlense optics.

- Diffuse reflectance spectroscopy and multispectral imaging for in-vivo diagnostics of

skin vascular and pigmented lesions.

- RGB imaging for mapping of skin chromophore concentration.

- Obtaining and exploring the parametric images of autofluorescence fotobleaching

distribution in time and chromophore fluorescence lifetime distribution imaging.

- Research regarding optical properties of skin chromophores, mostly bilirubin,

including in vitro measurements of different substances in order to find spectra that

are similar to the spectra of skin chromophores (bilirubin, hemoglobin) and that are

stable in time.

- Study of blood microcirculation in skin with multi-spectral photoplethysmography at

465/530/780 nm (BRIR laser diode device) and at 465/530/630/870 nm (RGB and IR

LED device)
