Therefore the reflected light is sensed by the sensor 13 and the lattice pattern is read therefrom. Meanwhile, a distance of movement of the stage 2 and the material 8 in the direction of the Y axis is read even for 1/1000mm on the operation unit 12 side from the rotation of a Y-axis pulse motor 4. Therefore a read signal from the sensor 13 and a position signal from the unit 12 are processed by a signal processing device 16 and an interval between lines of the pattern 9 of the material 8 is calculated. By this method, a surface strain of a tire can be measured automatically and quickly.
