Aa. Benditskii et al., MEASURING THE DIMENSIONS OF BODIES OF COMPLEX SHAPE USING AN OPTOACOUSTIC RANGING METHOD, Measurement techniques, 40(3), 1997, pp. 230-232
A description is given of an automatic apparatus for measuring the dim
ensions of objects of complex geometrical shape using an optoacoustic
ranging method. The results are given of measuring the dimensions of a
test object, a steam-turbine blade, and a shoemaker's last. An accura
cy of better than +/-50 mu m was achieved.
