TVDE 331 is based on TV holography (or ESPI-electron speckle interference technology，TV holography is based on laser interferometry）, is used for surface vibration and static deformation of the audience non-contact measurement.
TVDE 331 holographic vibration and static deformation sensor has these functions: Vibration and static displacement, full field amplitude and phase diagram, animation display, pattern analysis, real-time function.
The TVDE 331 system supports 2D and 3D displays. Test objects as small as a few centimeters, as large as a few meters. The amplitude can be as small as 1nm.
High frequency High sensitivity；
2D and 3D display;
