Photonics
Group
We develop and calibrate optical imaging systems to explore spectral, polarization and infrared information — from laboratory measurements to material, biological, environmental and astronomical applications.
Our focus
More information in every image.
01 / Spectral
Hyperspectral
imaging
Colour, multispectral and hyperspectral imaging of materials, plants, food and printed surfaces.
Explore the methods
Reflectance calibration, spectral feature extraction, focus stacking and image classification.
02 / Polarization
Polarization &
infrared imaging
Polarization sensing, infrared optics and acousto-optic tunable filters.
Explore the methods
Polarizer and camera development, acousto-optic filter modelling, optical measurements and system calibration.
03 / Computation
Calibration &
image analysis
Connecting optical design and physical models with image processing and machine learning.
