An experimental set-up elaborated for distance measurement with a use of a laser optical displacement sensor has been described. The features of the elaborated device allow to measure a surface roughness and dimensions of small details. Elaborated computer software allows automatically to estimate the classical surface roughness indices. The surface roughness indices can be estimated also for sloping planes. A solidification surface profile in macro and micro scale can also be measured. The mentioned solidification surface profile is measured on solidified shells obtained by using of so-called remove remainder test. Exemplary measurements of mould and casting surface roughness have been presented.

An experimental set-up elaborated for measurement of solidification surface profile of metal stream flowing in a mould channel has been described. The mentioned solidification surface profile is measured on solidified shells obtained by using of so-called remove remainder test. As measurement result one obtains a line showing shells thickness distribution along their length. For shells thickness measurements a laser optical displacement sensor has been used. Using of the laser sensor allows also to observe the solidification profile line in micro- scale. Exemplary measurement results have been presented for Al-Si binary alloys.
