The 4DSkin solution enables non-contact deformation measurements to be made over large areas of up to several kilometers at high frequency (typically every 2 minutes) and a very high level of accuracy (typically 0.2 mm).
4DSkin: Contactless Deformation Measurement
4DSkin provides simultaneous remote measurement of thousands of data points over large areas without the need to access the area under observation. Measurement accuracy ranges from 0.1 mm to a few mm for data points up to 3-4 km distant, regardless of weather conditions.
4DSkin generates displacement maps of all pixels in the area and time-based graphs tracing the evolution of each pixel.
4DSkin is based on the use of interferometric synthetic aperture radar technology.
4DSkin's Applications
