Abstract

PURPOSE: To find the surface waveform of a beltlike body in process of conveyance quantitatively with accuracy even if the above waveform would appear to be at a stop, by providing the method of projecting a bright line of not less than one waveform and that of taking a picture of an optical image deformed by the waveform.
CONSTITUTION: In parallel to beltlike body 10 conveyed as shown by arrow A, projector 14 projects a linear bright line 12 longer than at least one wavelength of the waveform. Then, picture 16 deformed by the surface waveform is obtained by pickup unit 18. Next, displacement value h of beltlike body 10 from support surface 11 under it is calculated to detect the waveform.
