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 each pixel.
4DSkin is based on the use of interferometric synthetic aperture radar technology.
