At the present moment an original SMIP for non-contact control of initial surface profile and measuring its deviation from the specified one or its variation in the process of construction loading has been developed. SMIP sensitivity allows to control displacement of the construction profile from the specified one at the level of (5~10)×10^-6m with the extention of test zone controlled by one SMIP up to 3m.
目前已研制了一台SMIP原型，用来对初始表面轮廓线进行无触点控制，并测出其偏离规定外形的量，或测出外形在结构承载过程中的变化量。SMIP有很高的灵敏度，可将结构外形偏离规定外形的位移量控制在(5~10）X10^-6米的量级，而且一个SMIP控制试验区的范围可达三米。
With the help of SMIP tests of a number of aircraft were performed and unique data on the behaviour of constructions under loading and during fracture were obtained.
SMIP proved efficient for non-contact investigation of vibro-displacement fields of the construction, their frequency response, forms of oscillation and phase ratios between oscillations in different points of the construction.
借助SMIP，对多架飞机进行了测试，获得了在承载条件和破裂情况下关于飞机结构性能的独特数据。
SMIP已表明对于结构振动一位移场、它们的频响特性、振荡的形态和结构上不同点之间振荡的位相比等项测试的无触点实验研究是有效的。
The level of sound pressure in the area of SMIP location can achieve 160 db. The rate of inquiry in this investigation was 10^5 Hz. The transducer is located at some distance from the surface during the profile control as well as the vibro-displacement investigation and does not affect its stiffness characteristics. The amount of information recorded in the computer memory during such investigations is equivalent to the amount of information that could be obtained with the help of several thousand tensoresistors and displacement gages. Hardware expenses are also non-commensurable.
It is obvious that SMIP has a great future, and the capabilities of these transducers are still to be studied, as well as spheres of application.
SMIP所在区域的声压级可达160分贝，本次研究的采样率是10^5赫兹。在外形控制以及振动一位移实验研究中，传感器都位于离开表面某一距离的位置上，因此，不会影响结构的刚性。在这类研究中计算机存储器上所记录的信息量与利用数千个张力电阻器和测位移计所能获得的信息量相当。而硬件的花费却是不能与此相比的。
显然，SMIP很有前途。这些传感器的能力及其应用范围还有待进一步研究。
