摘要： In a non-contact type of strain meter adapted for measuring a strain of a measuring object on a non-contact basis, two laser Doppler velocimeters are arranged in such a manner that velocity V A and velocity V B involved in a measuring direction (X-direction) on points A and B of the measuring object are measured, and the points A and B of the measuring object are set up in such they are in line in the X-direction at an interval of a distance L. Velocities V A and V B on the point A and B in the X-direction are evaluated. The velocities V A and V B thus obtained are integrated to evaluate associated displacements X A and X B , respectively. A strain ε is evaluated in accordance with the equation: ε = ( X B - X A ) / L
