Lighting
Light source for image processing systems. Different lighting types and → lighting techniques must be taken into account. Other properties to be considered are: Direction of propagation (diffuse, directional, parallel, telecentric), wavelength / color (UV, VIS, NIR, IR), → illuminance, homogeneity, → polarization, flashed or static.
The type of lighting depends on what you want to focus on in the final image.
The lighting setup for a specific application will generally have to be done individually on the basis of experiments (empirically). It is therefore hardly possible to draw up general guidelines for this. However, the experimental approach is considerably facilitated by basic knowledge of various lighting methods.
LED lighting is usually used as the light source.
