Photonics Dictionary

machine vision illumination systems: Machine vision illumination systems are specialized lighting setups designed to optimize the performance of machine vision systems. These systems are crucial for capturing high-quality images and ensuring accurate analysis and interpretation by machine vision algorithms.

Light sources: Machine vision illumination systems typically use various types of light sources, such as LEDs (Light Emitting Diodes), halogen lamps, fluorescent lights, or lasers. The choice of light source depends on factors like the application requirements (e.g., wavelength sensitivity), energy efficiency, and durability.

Optical elements: These include lenses, diffusers, filters, and polarizers that modify the characteristics of the light emitted by the source. They help control aspects such as intensity, uniformity, and directionality of the light to optimize image quality.

Control systems: Machine vision illumination systems often include control mechanisms to adjust parameters such as brightness, color temperature, and strobing frequency. This flexibility allows adaptation to different imaging conditions and object characteristics.

Integration with machine vision systems: These illumination systems are designed to be compatible with cameras and other sensors used in machine vision setups. They are positioned strategically to minimize glare, shadows, and other image artifacts that could affect the accuracy of image analysis.

Application-specific designs: Depending on the application, machine vision illumination systems may be customized for specific tasks such as surface inspection, object recognition, defect detection, or measurement tasks. Specialized designs may include structured lighting patterns or multispectral illumination to enhance detection capabilities.
