Abstract
Correlation among gravimetric, spectrophotometric and radiographicdata from dried wood samples of Scots pine (Pinus sylvestris L) wasobserved. A diffractive optical element (DOE) based sensor was applied toinvestigate density variations as well as optical anisotropy inside year ringsof the wood samples. The correlation between bulk density of wood andspectrophotometric data (reflectance and transmittance) was investigated for thewavelength range 200-850 nm and the highest correlation was found atwavelengths from 800 to 850 nm. The correlation at this wavelength was smallerthan the correlation between bulk density and radiography data. The DOE sensorwas found to be capable of sensing anisotropy of the wood samples inside theyear ring.
