| Abstract: | HeNe laser light components scattered through small wood samples from Scots pine (Pinus sylvestris L.) were investigated using a diffractive optical element (DOE) sensor and the optical signals compared with optical density data extracted from x-ray negatives of the respective samples. Good agreement between the x-ray and optical signals was observed with respect to the gravimetric density of the Scots pine samples. Received 20 January 1999 |
