Fringes projection (Figure 1) consists in the projection of a network of fringes of different sizes onto the test area. The fringes are distorted according to the relief. After four data capture sequences, the height of each point is calculated and the software reconstitutes the three-dimensional profile of the investigational area.
Cutaneous replicas are useful tools in dermatology and cosmetology. Many measurements are obtained with this rapid technique which does not require the volunteers' presence for a long time. It can be performed at any age and repeated several times on the same area of the skin.
