This study investigates a new 2-dimensional phase unwrapping method named RIPI (Regional Identification, partition and Integral phase unwrapping method), which is aiming at the problems of "line-draw" and loss of useful data while phase unwrapping in processing moiré interferometry experiment images.

The technique of carrier modulation in Moiré interferometry is important in displacement measurement of an object.

Meanwhile, as a rapidly developing technique of photomechanics, moiré interferometry has attracted attention for its advantages of high sensitivity, excellent contrast, noncontact, real time, whole field, e.

The moire interferometry method and moire interferometry-finite element analysis hybrid method have been applied to study interface fracture behaviors of bimaterial specimen which is simulated to porcelain-Fused-to Metal (PFM) restoration.

The thermal strain of bimetal soldering joint (Cu and Kovar) is analysed with moire interferometry method.

Moire interferometry is an optical measurement which is noncontact and has big measuring range, wonderful fringe quality, real-time whole field measurement and high sensitivity, so it can measure the physical quantities about the tiny displacement and strain field of the surface of specimen accurately and effectively.

Investigated stresses were relieved by cutting specimens along a radial direction, and additional strain fields created by relieving the stresses were measured using moire interferometry.

The residual stress distribution around cold expanded holes was measured by moire interferometry,the influence of reaming and fatigue on the residual stress were investigated experimentally.

Study of creep deformation of metal materials with moire interferometry;

Thermal deformation measurement of solder joints in surface mounted technique components using Moire interferometry;

It is mainly about using the wave front interference principle of Moiré interferometry analyzed the possibility of non-contact measuring elastic modulus and Poisson ratio for high temperature materials by Moiré interferometry and the types of grating specimers of Moiré interferometry in high temperatures.

This paper proposes a method where displacement data measured by moiré interferometry instead of the strain information are used, and finite element method was used to establish the relationship between the displacement and the residual stress.

A combined method of moiré interferometry and incremental hole drilling was conducted to study non uniform residual stresses,calculation formula and the experimental technique were presented.
