Radiometry
The focus areas of Metrology Research Institute in radiometry include optical detectors, radiation sources, and the radiation transfer through various media. Group's recent research areas form a cross-disciplinary combination of LED based light sources, lifetime of optical components and materials, renewable energy sources, atmospheric radiation propagation, and environmental measurements.

Detection of power of electromagnetic radiation is essential for nearly all scientific and technical fields that use electromagnetic radiation for either research or industrial purposes including applications in health, safety, and security. Because of the lack of a suitable power detection scheme which is capable of sensing incident radiation over a wide spectral range, several other approaches have been developed among which photoacoustic (PA) technology is one of the potential methods.

Calibration of Near-Infrared Detectors Using a Wavelength Tunable Light Source
Calibration of optical detectors is important for the reliability of optical characterization methods and therefore, has significant applications in optics and metrology. We have developed a portable wavelength tunable light source to calibrate the spectral power responsivities of detectors in the infrared region.
Metrology Research Institute studied the calibration methods of hyperspectral cameras in collaboration with Finnish Geospatial Research Institute (FGI) within Academy of Finland project "Quantitative remote sensing by 3D hyperspectral UAVs – From theory to practice". This activity resulted in two calibration services – Flat field calibration of the spatial responsivity, and characterization of the spectral responsivity of cameras.
The operating temperature of light-emitting diodes (LEDs) affects their lifetime. Metrology Research Institute has developed models to help estimate the junction temperatures and lifetimes of LEDs.
