Are you wondering what is automated optical inspection? Optical inspection as its name suggests is for inspecting the optical surface and digging out errors in the same. When humans do the same it is called manual optical inspection. On the other hand, when done with the help of machines, it is called automated optical inspection. Different standards are used for the same in the case of automated optical inspection. These standards are mainly dependent upon three principle aspects which are described in detail below.
Top Three Principle Aspects Used For The Working Of Automated Optical Inspection
• Illumination
One of the key aspects when it comes to optics is illumination. Be it through naked eyes or machines, it is not possible to detect the surface defects unless illuminated with light. There are different light sources that machines use which include incandescent, ultraviolet and infrared light. Nowadays LED light source is more preferred over others as the amount of light can be controlled.
• Machine Vision Cameras For Capturing Images
Imagine identifying the spot having defects and not being able to find it afterward. The same equipment has image capturing devices that send analysis to the machine. Usually, high-definition cameras are installed for better performance and detection. So another vital aspect of AOI machines is machine vision cameras which are present in both 2D and 3D AOI.
• Processing Software For Information Processing
The machine should know about the object being inspected. For the same information about it is set into the machine for its analysis. It helps the machine to analyze the different aspects of the product. So make sure to process the information for proper analysis of the product by the machine.
These are the principal aspects found in any type of automated optical inspection machine. There are various advantages of the same as it reduces strain on human eyes. All the required detection is done with the help of AOI and the manufacturing process can be improved through it. Another method for improvement of AOI is the use of inline 3d spi.
