LABORATORY OF VISUAL PERCEPTION
Head of Laboratory Prof. M.Ozolinsh
Human vision is a complex phenomenon. Its optical part is essential, however optical
image stays only at the very beginning of the visual pathway and information processing
in the cortex. We see with our brains, and as a result in some provocative cases it is very
hard for us to accept the final outcome. Laboratory is a joint between colleagues in
institute and Department of Optometry and vision science of the University. Most of
Department’s Master thesis have been accomplished due to collaboration between units.
In 2012 more than 20 Bachelor’s and 10 Master’s thesis have been completed under
supervision of laboratory researchers.
Research in laboratory is focused on following problems:
- investigation of smart optical materials and designs with controllable optical,
electrooptic, refractive properties such as pjezooptic and electrooptic materials in order
to accomplish effective radiation wavefront control, modification of light scattering and
other optical characteristics;
- effect of aberrations in eye structures and appliances on retinal image formation and on
the psychophysically detected human visual response, accomplishing adaptive optics
compensation of optical objects aberration errors with fast control feedback;
- studies of binocular and stereovision, suppression and rivalry mechanisms of
binocular vision, evaluation of suppression strength and depth effect on quality of vision
binocular functions;
- fast eye kinematics studies for children and adults without and with several disorders
of visual perceptions, eye kinematics studies in sport vision.
- evaluation of accommodation/convergence mechanisms reading print materials and for
regular computer users;
- digital visual stimuli image processing determinant for analyse of the human visual
response;
- multispectral material surface reflectance and emission analysis in visible and near IR
and UV range, and its visual recognition by humans with normal and colour deficient
vision;
- providing illumination and material visual appearance testing expertise and quality of
products correspondence according to standards.
