Angle-resolved measurements of optical material properties
|Coordinator||RISE Research Institutes of Sweden AB - Mätteknik Borås|
|Funding from Vinnova||SEK 555 000|
|Project duration||January 2019 - December 2020|
Purpose and goal
In order to meet an existing industry need, which is clear e.g. in the automotive industry with new types of glass with changeable properties for optimizing active system sensors, the NMI wants to improve the methodology and performance of our BRDF (Bidirectional Reflectance Distribution Function) measurement system, and also develop a new system for traceable measurements of BTDF (Bidirectional) Transmittance Distribution Function).
Expected results and effects
In addition to enabling new services for the benefit of the industry by providing traceable measurements of BTDF and BRDF, the outcome of the project will make the NMI group a more attractive partner for future research projects. Also, within a few years from now the hope is that both BRDF and BTDF will be well-defined and established quantities, thus enabling the NMI to expand its existing CMCs.
Planned approach and implementation
The NMIs existing measuring equipment for BRDF will be optimized and validated. For BTDF (with normal incident radiation), a new automated system will be developed, partly based on existing equipment. This includes design, control, data collection, methodology and validation. The latter will partly be carried out by the NMIs participation in an upcoming related EMPIR project.
