Machine Vision - Lighting: CCSA-QSQ-070070-SW Application Field and Working Principle

The use of Machine Vision (MV) lighting is becoming increasingly popular as a method of illuminating objects during image processing and acquisition processes. Machine vision lighting, such as the CCSA-QSQ-070070-SW, consists of a wide selection of lighting components including controllable light sources, lenses, cameras and software modules. To ensure quality image acquisition, MV lighting is used to provide both direct and diffuse illumination for target objects.

Application Fields of Machine Vision Lighting

The application fields of MV lighting primarily include inspection, guidance, navigation and tracking. It has been used successfully in many fields, such as automotive, medical, printing, precision engineering, surveillance and security, material handling, food processing and biometric recognition. The use of suitable lighting is essential for increasing productivity, quality, and safety in these applications.

Working Principle of Machine Vision Lighting

The main working principle of MV lighting is to accurately strike the target object with the appropriate illumination for detection or measurement. In practice, the goal is achieved by the selection of the optimal illumination type and configuration. This includes selecting the most suitable light sources, lenses, filters, radiation devices, and software modules.

When selecting an appropriate light source, a few details such as light wavelength, luminance, angle of lightray, and spectral content must be taken into consideration. Generally, an LED is the most suitable light source for MV lighting, because it has the least impact on the environment and can be used for a long time with relatively low power consumption.

Lenses are also essential in MV lighting because they enable better control of the light rays reaching the target object. The selection of lenses depends on their focal lengths, Numerical Aperture, combination lenses, etc. Using a combination of lenses which ensures a good contrast between the target and its background is important for obtaining a better image.

Filters are used for blocking out irrelevant light rays or the wavelengths which can cause interference in the image acquisition process. Depending on the application field, the most suitable type of filter must be identified. They are usually mounted between the light source and the camera.

The most suitable radiation devices are also essential for optimizing the light rays to the target object. Depending on the application field, collimators, concentrators, baffles, and shields are commonly used for MV lighting.

Software modules are a necessary component of MV lighting. They are utilized to control the illumination components and configure the system. It is worth mentioning that the quality of the software and the features available for configuration are important factors for achieving good image acquisition.

Conclusion

Machine vision lighting, such as the CCSA-QSQ-070070-SW, is widely used in many application fields. Using the appropriate light sources, lenses, filters, radiation devices, and software modules can significantly improve the image acquisition process. Furthermore, understanding the working principle of MV lighting is the key to selecting the most suitable components and configuration.
