CONSTITUTION:Laser light LO from a semiconductor laser 1 is condensed at the position of the focal point of an optical lens 2 5 through a collimator lens 2 and a beam splitter 3. Part of the condensed laser light LO is transmitted through optical glass 4 and projected on a reference surface S. The other part becomes the reflected light beam L2 which is reflected from the glass 4. The reflected light beam L2 is inputted into a photodetector 6 through the lens 5 and the beam splitter 3. Then the reflected light beam L1 which is reflected from the reference surface S is inputted into the photodetector 6 through the lens 5 and the beam splitter 3. The reflected light beams L1 and L2 are made to interfere and synthesized in the lens 5. The brightness of the circular interference fringes is changed by one period every time the reference surface S is displaced in the direction Z by lambda/2. Therefore, the signal of the brightness is detected with the photodetector 6 and transduced into the electric signal. The signal is processed, and the amount of the displacement in the direction Z can be found.

Next, the rolls 2, 3 are opposedly disposed, and a long-sized material 1 is placed between these in the position of 90° in θ, and the rolls 2, 3 are revolved while the inter-shaft distance l is being maintained. Thence, the radii R of te rollers 2, 3 increase linearly between 90° and 270°, whereby bending is progressed. Thence, the final bending takes place in a constant range of the radii R between 270W360° of θ. The rolls are further rotated 90° and at the same time the long-sized material 1 is pulled back by the length corresponding to the roll rotating angle 360°. Then, the bending is completed by the difference between the pull back length and the bending length. The long-sized material is bent by repeating this process.
