Light projected from the light source projects through the mask (140). The projected light through the mask (140) may be a collimated pattern which does not significantly change in size as a function of the distance to a projected plane. The projected light patterns may include multiple wavelengths of light for measurements of different features of tissue and may be produced using a laser in conjunction with a light shaping optical diffuser, or using a light emitting diode in conjunction with a light shaping optical diffuser, or using a spatial filter. The projected light patterns may take the form of concentric rings with each ring representing a radius of a given dimension.3/4 180 190 ,-~100 175 170 130 "iP" 120------------- -110 135 140 FIG. 3
