The high-resolution and frame speed combination with CMOS image sensors is very attractive and the major driving factor towards the move to CMOS with industrial cameras. A consideration with CMOS image sensors are the different types of defects present and whether the camera manufacturer corrects for them.
With higher resolution and frame speed, the latest machine vision cameras can improve accuracy and increase capabilities with 3D measurements. One of the challenges can be transferring this high data rate to the frame grabber and processing system. Many advances have been made with Camera Link to increase data rates, but this can come at…
In electronics manufacturing, a common measurement technique is Automated Optical Inspection (AOI) 3D AOI, which offers significant improvements over 2D.
Before any transistor is laid down, the incoming silicon wafer must be analyzed for flatness and defects. From this inspection, wafers can be classified to allow the best wafers to be used for the smallest technology node. Typically measurement techniques such as interferometry are used for this. Extremely stable cameras with low noise are needed…
Traditionally machine vision cameras are designed that the data rate of the image sensor should match with the frame grabber or PC. But common image data rates will soon exceed 10Gbit/s and move up towards 30Gbit/s over the next years. This means that high performance interface solutions are needed in order to access the full…
When a full color image from the machine vision system is required for accuracy, there are several advantages for having color processing right in the camera. But, creating color images you can rely on is not as easy as it seems, especially when the image must represent the actual color of the scene.
Flat Field Correction (FFC) processing can be used to minimize or even remove artifacts to improve the image uniformity. The purpose of flat field correction is to ensure image uniformity regardless of exposure.
Their excellent image quality combined with a robust design means machine vision cameras find homes in some unique and demanding applications beyond manufacturing and measurement instruments.
