Abstract:
    The present invention relates to a device using laser disperse spot shearing interference method to measure the tread deformation and the touchdown pressure in the tire touchdown plane. The measuring device of the present invention is configured in such a way: after the tire and the knurl are fixed on the acrylic panel irradiated by laser, the coherent beams of laser or the like are irradiated thereon; the phase diagram of the light irradiating to the tire surface is obtained; thus the differential value of the object surface dislocation corresponding the physical quantity is obtained quantificationally. The present invention adopts the universe descriptive laser disperse spot shearing interference method which obtains the deformation distribution by nondestructive checking method, and adopts a structural characteristics of using the common light path.
