Overview

SAMBA Face system is an instrument dedicated to the measurement of in-vivo skin gloss, directly on the model body (face, arm, etc.). Its purpose in the cosmetic industry is to substantiate claims and evaluate products efficacy such as make-up, foundation, skin care products, on every type of skin.

The SAMBA Face System includes our SAMBA camera, a polarized LED illumination, a chin-rest  and computer with our own software, allowing the user to acquire the measurement in one click. A complete analysis (numerical data and images) of the visual characteristics (gloss, color, images, etc.) is delivered in seconds.

All those data and images can be quickly compared and exported for reports, presentations or post processing.

Principle

SAMBA Face system acquires successively 2 images of parallel and crossed polarization state. This allows the decomposition of the image seen by a conventional camera or the eye into 2 images: Specular and Diffuse.

The specular image only contains the light reflected by the skin surface. Skin surface texture and defects like wrinkle can be easily observed. The diffuse image only contains the light scattered by the skin sub-surface.
