Skin Imaging Protocol

The skin measurement device is comprised of a Sony DFW-V500 IEEE-1394 digital camera equipped with InfiniMini video lens with variable focus from 750mm to 150mm, and video magnification 2.9-15X, a rheostat controlled high intensity quartz halogen illuminator, a personal computer running Windows 2000 with IEEE-1394 digital camera Windows driver (available freeware at URL http://www-2.cs.cmu.edu/~iwan/1394/).

Various camera poses are obtained by using a tripod and a manually articulated arm. The light source is positioned by using a rotatable positioning arc, which ensures constant distance between surface of interest and light source. The lamp is positioned distant enough from the surface of interest such that an approximative collimation of light is ensured. In order to monitor the light intensity across various imaging sessions, a white diffuse reflectance target providing an extremely flat spectral response in UV, VIS, and IR, is imaged during each imaging session.
