Abstract : A method was developed which permits an approximate measurement of vertical deformations in wood panel surfaces. A narrow slit of bright light directed at a tightly stretched wire so as to cast a shadow on an inclined test surface. A photograph, taken from directly above, reveals any irregularities by the form of the shadow so cast.
