Abstract
The invention concerns an arrangement for determination of the shape of a measured object's surface. A position sensitive detector 3 includes a first position-sensitive detector 31; 18 and a second position-sensitive detector 32; 19, which is two-dimensional; the arrangement includes a beam splitter 10 to divide the beam reflected from the measured object's surface into a first beam 11 to the first detector 31; 18 and a second beam 12 to the second detector 31; 19 [sic]; magnification optics 13 to magnify the image of the second beam 22 and for shaping the image region 21 of the second detector to a part of the first detector's image area 20 determined by the magnification of the magnification optics; the first detector 31; 18 is arranged for crude position determination for the second beam's 12 image alignment in the second detector's 32; 19 image area in cooperation with transport device 6; 17; and a data processing device 7 is arranged to determine from the second detector's 32; 19 image area 21 the second beam's 12 image 22 position and based on this to make the results of the determination more precise by calculation than the value obtained from transport device 6; 17. <IMAGE>
