However, this very intuitive and simple approach often fails due to many problems, such as invalid areas and inconsistent data in the wrapped phase map, undersampling of fringe patterns, and unavoidable noise.
Examples show that it can deal with invalid data as well.
It verifies the effectiveness of the proposed filtering scheme in noise reduction.
The effectiveness of the propose approach in removing the noise and localizing the influence of invalid data is verified by real and simulated examples.

LabVIEW is a graphical language suitable for data acquisition and information control, its program structure is data stream, which decides the operation sequence of procedure.
Hardware frame of the experiment system The hardware of vibration measurement and fault diagnosis system is a programmable data acquisition system, which includes vibration tester, sensors, signal conditioning instrument, DAQ card and computer, as shown in Fig. 1.
For obtaining exact characteristic parameters for fault diagnosis, data pretreatment methods and feature extraction methods can be combined arbitrarily according to the need.
For example, combining correlation analysis with demodulation analysis, the time delay correlation demodulation method can be got, which has a good effect on noise reduction and demodulation.
In the process of acquiring and processing experimental data, students can apply relevant theory into the practice of measurement and diagnosis and grasp the relevant knowledge.

Table I shows the Dit data collected at 0.1 eV below the 4H-SiC conduction band, which decrease with increasing the NO annealing duration with a saturation at about 4×1011 cm-2eV-1.
The relevant data reported in Fig.4 are also summarized in Table I.
Fig.4: NTrap values (calculated from data shown in Fig.3) obtained on the MOSFETs subjected to PDAs in NO of different duration.
Table I: Survey of the electrical data collected on the investigated MOSFETs.
By a cross-comparison of all the electrical data summarized in Table I, it is possible to conclude that prolonged NO PDAs may induce detrimental effects.

As a result of the experimental study of the process of draft of inhomogeneous material in a closed matrix, the data characterizing the pore formation and distribution of forces depending on the friction factor, the deformation rate and the degree of deformation are obtained.
The obtained experimental data can be used to construct a model describing the deformation of an inhomogeneous medium taking into account the compressibility of the material.
Similar data were obtained for the rest of the considered pores.

There are many measures of the energy consumption reduction.
The work in the paper used the experimental method to verify the effectiveness of the resistance reduction and energy saving[2].
Through the related datum, according to the hull lines of parent ship, this paper designed the model of SSD[4].
When the speed was 14.5kn, the open angle of profile was 12°, and the distance between the SSD and the propeller disc was 40mm, the received power decreased the most, the value reduced from 7076 to 6810, the amplitude reduction was 3.8%.
