Besides optics, the illumination is an important point, which is critical for good results in the image
processing. The golden rule is: create contrast.
A lighting system can be homogeneous or structured. Following table shows the effects and the
characteristics of lighting systems:
• light on object
• light as a contrast to the object
• no information by the light
• information from the object
• must be homogeneous
• must be time stable
• must be broadband in
color
• underlines specific characteristics
• color changes contrast of details
• projected lines perform a
coordinate transformation
• usually disturbing reflections become
information
• is definied structured
• is limited to light bands
