Description: The challenge is to develop a method for measurement of optical response signals in the ultra violet (UV) wavelength range to define properties of the fibrilled cellulose fibre. The optical processes involved in the measurement method are transmission, absorption, diffraction and scattering, depended nt ofn the properties of measured object. The method is extended to an extreme ultra violet (EUV) radiation field with a wavelength of 13.5 nm to be able to resolve smaller particles.

Sensitive detectors for measuring optical signals as well as detectors for measuring the optical beam position in EUV radiation fields are therefore developed and characterized. The project is carried out in close collaboration with Pulpeye AB, SiTtek Electro Optics AB and MAX-lax Lab.
