Measuring device and measuring method for auxiliary standard assembly of ground penetrating radar calibrating device

Abstract

The invention provides a measuring device and a measuring method for an auxiliary standard assembly of a ground penetrating radar calibrating device. Four linear guide rails are combined into a portable detachable three-dimensional displacement table and are the first linear guide rail, the second linear guide rail, the third linear guide rail and the fourth linear guide rail, wherein the first linear guide rail and the fourth linear guide rail are parallel to the Z axis, the second linear guide rail is parallel to the X axis, and the third linear guide rail is parallel to the Y axis; a laser interferometer and a linear interference mirror are fixed to the second linear guide rail; a linear reflector and a reflector fixing device are fixed on the third linear guide rail; and the incident light and the emergent light of the laser interferometer should be parallel to the Y axis and perpendicular to a measured flat plate. According to the invention, the motion error in the working direction is measured to compensate the final measurement result, the measurement positioning point is automatically searched, and the measurement process is automatic, so that the precision and accuracy of the measuring device are ensured, and the measurement time is greatly shortened.
