Even "white" light can be generated in many different ways. Depending on the problem, light requirements, object size, installation dimensions etc., different lighting is used:

Illumination lightingmeaning

The temperature of a colour is measured and indicated in kelvin (K) and is a measure for the colour impression of a light source. The spectrum visible to the human eye ranges approximately between 2,790 and 11,000 kelvin.

A special role in image processing plays LED lighting. Its characteristics such as durability, mechanical robustness, ideal arrangement capability in almost any housing shapes are ideal for machine vision purposes. Its light colour is not only white, but also red, green or blue, infrared or even ultraviolet. This allows for applications which would not be possible using other types of illumination. Therefore, many industrial machine vision applications are realised using LED illumination.

Each type of illumination has an individual light spectrum with a different distribution over the visible range of wavelengths with different intensity. An incandescent lamp does indeed have a complete spectrum which, however, has a typical bell-shaped intensity distribution of a "black body" radiator. Metal halide lamps, fluorescent lamps and LEDs even have very significant emissions in specific wavelength ranges.

The physical explanation for this phenomenon is the definition of a "black body radiator" according to Max Planck. A black body absorbs all incident radiation, i.e. it reflects no radiation. The colour temperature refers to the temperature of the black body which generates the same colour impression as the actually existing lighting.

Not every white light source seems to have the same shade of white for the viewer. In case of colour (as well as monochrome) camera systems, it can also be observed that the images have colour effects, or that grey values are shifted significantly.
