Illumination systems for image processing are a crucial component of many industrial applications. They play an important role in optimizing image quality and detecting details. This technical text introduces various illumination systems for image processing and explains their areas of application.
One of the most commonly used lighting techniques is backlighting. In this process, the object is illuminated from behind, highlighting contours and structures. Backlighting is particularly suitable for inspecting surfaces, as it makes irregularities and defects clearly visible.
Another popular method is reflected light illumination. Here, the object is illuminated from above or from the side to create shadows and gain depth information. Incident light illumination is well suited for measuring 3D objects or inspecting surface structures.
Ring illuminators are often used for macro photography or inspection of small objects. They consist of a ring with several LEDs that illuminate the object evenly from all sides. This minimizes shadows and achieves uniform illumination.
Diffuse lighting is another lighting technique in which the light is diffused evenly onto the object. This minimizes reflections and makes surface details visible. Diffuse illumination is particularly well suited for the inspection of shiny surfaces or transparent materials.
Polarized light is often used to reduce reflections and make surface details more visible. In this process, the light is sent through a polarization filter that only allows light in a certain vibration plane to pass through. This method is well suited for the inspection of plastics or metals.
In addition to the lighting techniques mentioned above, there are many other options that can be used depending on the application. These include, for example, UV illumination, infrared illumination or special light sources such as lasers.
The choice of the right illumination system is crucial for the quality and accuracy of image processing. Therefore, it is important to consider the requirements of each application and select the appropriate lighting technology. The right lighting can help detect defects, optimize production processes and improve product quality.
Overall, lighting systems play a crucial role in image processing. They enable more accurate inspection of surfaces, measurement of 3D objects and detection of details. Selecting the right lighting system can improve image quality and increase the efficiency of industrial processes.

1. Incident light illumination: With this type of lighting, the light is directed onto the object from above. This creates strong shadows and can be used to detect surface details or defects on the object.
2. Transmitted light illumination: Here the light is directed through the object from below. This type of lighting is well suited to capturing the transparency or permeability of the object.
3. Ring lighting: With ring lighting, a ring-shaped light source is placed around the object. This creates uniform illumination without shadows and is well suited for the detection of symmetrical objects.
4. Grazing light illumination: This type of lighting creates streaks of light on the object. This can be used to detect surface defects or to emphasize the texture of the object.
5. Backlight: The light is directed onto the object from behind to create a silhouette of the object. This type of lighting is well suited to capturing the contours or edges of the object.
6. Coaxial lighting: With coaxial lighting, the light is directed perpendicular to the surface of the object. This directs the reflected light directly back to the camera, which helps to minimize reflections or highlights.
These are just a few examples of the different types of lighting systems used in image processing. Depending on the application and the specific requirements, combinations or specialized lighting systems can also be used.
