How to select CoaXPress cables for machine vision and multi-camera systems

The continued adoption of CoaXPress in machine vision inspection and metrology systems is partially due to the higher video data rates enabled.  But in multi-camera systems, the smaller more flexible cables are an advantage to fit in tight spaces and enable moving heads. An overview of the possible CoaXPress connector types For many CoaXPress imaging…

Read noise versus shot noise – what is the difference and when does it matter?

When determining the best metrology camera, one of the first considerations is to determine the dominant noise source.  This can help you prioritize the most important camera parameters, such as sensitivity or dynamic range. In this post we will consider temporal noise sources that vary with time including shot noise and read noise. With this, it…

CCD versus CMOS: blooming and smear performance

For many years CCD image sensors and cameras have offered advantages in image quality such as greater dynamic range, better noise performance, and better uniformity. For this reason, CCD cameras were still used in many of the most demanding machine vision systems needing the highest accuracy or in global security systems where sensitivity in low…
