FOITS <sub>HD is an optical method for non-contact measurement of skin microtopography. This is realized by a combination of Gray code and phase shift technique.

Various parameters like Rz or Ra are used in order to describe the effect of an anti-ageing product. Very often discussed, but not really used in routine work, the volume of wrinkles is still a challenge in the field of claim support for cosmetic products. 3-dimensional data have to be available in high resolution to ensure a realistic and scientific analysis of facial structures. By defining and analyzing volume changes in facial wrinkle evaluations a key factor in the link of illusions (consumer’s view) and facts (scientific view) can be established.

Introducing the FOITSHD technique, the next generation of Fast Optical in vivo Topometry of Human Skin in High-Definition is presented. This excellent tool with a noise reducing and resolution increasing setup allows a new way of volume definition just as analysis of facial wrinkles in vivo in a touch free measuring geometry.

This the analysis of single wrinkles as well as the overall volume can be investigated. Results can be compared to basic line parameter like Rz or FDD (Frequency Distribution of Depth).
