Densitometer and method for measuring optical density |
摘要 |
<p>In methods for measuring optical density, the color on an area is determined (10) and based on the color, at least a first illumination source is selected (15). The area is illuminated with the selected illumination source (20). Radiation is received from the area (25), and the received radiation is converted to a signal of optical density (30). <IMAGE></p> |
