The principle of RUMBA is based on the measurement of the orientation of the hair fiber for each pixel of the image using polarization imaging. RUMBA image resolution allows single fiber imaging. At a pixel level each hair fiber can be locally decomposed into a linear direction defined by an angle versus the vertical direction (Picture below), that can be color coded.

For a complete hair tress:

A user-friendly software (left screen shot below) allows the user to acquire the measurement in one click. A complete analysis (numerical data, histogram and images) is delivered in seconds. Numerical data, histograms and images can be quickly compared and exported for reports, presentations or post processing.
