Measuring method using photoelastic analysis for finding touching point between ball and track profile
The elaborately calculated method of the present invention using photoelastic analysis for finding contact relation between ball and track is characterized in that a photoelastic plate having a semi-circular section is used in measurement by observing contrast of stripes appeared thereon in stead of observing track profile from the plucked image of the object in conventional technique therefore being released from shortcoming of inaccurate measurement result due to vagueness of profile of plucked image.
