Application of Penta Prism in Establishing the Datum Plane for Measuring Flatness in Large Scale Dimension
According to the operating principle and characteristic of pentagonal prism, it is analyzed that the fabrication error of the prism angles and the effect of lateral displacement of exit beam when the prism has a motion relative to the incident beam on the accuracy of the datum plane to be established. The Fresnel diffraction imaging technique is used to eliminate the effect of the lateral displacement and data calculating is used to calibrate the fbrication error of the angles.
