1000 frames per second cameras: Fast frame rates with ultra high resolution industrial cameras

The latest ultra resolution industrial image sensors offer impressive pixel throughput, such as 25 Megapixels at 72 frames per second. These pixel rates can no longer be transferred to the PC via Camera Link but can via interfaces such as CoaXPress (CXP). The resulting cameras can offer faster frame rates at lower resolutions through the…

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 vs. CMOS – Modulation Transfer Function (MTF) in NIR

We have been reevaluating the strengths and weaknesses of CCD and CMOS looking at the latest generation industrial image sensors and subsequent cameras. We have compared sensitivity, read noise, and blooming and smear performance. Now let’s consider the Modulation Transfer Function or MTF… The MTF of optics, say a lens, is the reduction in modulation…

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…
