Abstract

A test model for simulating one or more physiological parameters is provided. In one example, the test model includes a model layer having a test surface, a shaft rotatably disposed within the model layer and at least first and second contrast segments circumferentially disposed on the shaft. The model layer models at least one optical property of human skin, such as transmissivity of at least a particular wavelength of light transmitted into the model layer. The first and second contrast segments have contrasting optical properties with regard to at least the particular wavelength of light, such as reflectance. Rotation of the shaft causes different contrast segments to face the test surface of the model layer at different times.
