Phase change correction (PCC) is an important correction value of the end effect in an optical interferometry system. Normally, this value is used to compensate for gauge block measurement by an optical interferometry system based on ISO 3650:1998. T

Changes in stresses and pore pressure induced by tunnel excavation in low-permeability soil inevitably lead to further ground displacements following the construction. This can be referred to as consolidation ground displacements, which usually take

Following a tunnel excavation in low-permeability soil, it is commonly observed that the ground surface continues to settle and ground loading on the tunnel lining changes, as the pore pressures in the ground approach a new equilibrium condition. The

The LVDT probe is a very important component used in gauge blocks calibration via a mechanical comparative method. The probe is used to determine the central length difference between a reference gauge block and gauge block under-tested (UTC). Typica

The length difference between two gauge block were measured by using Michelson interferometer with stabilized He-Ne laser at 633 nm. The phase-shifting method was employed in order to create four interferograms. All interferograms were acquired by CC

A Rubidium (Rb) stabilized diode laser has been developed and has been used as standard wavelength to determine length of gauge block. The Rb stabilized diode laser is composed of an external-cavity tunable diode laser, (Toptica), EOM, and spectrosco
