Flat-Field Correction (FFC) can be done with both CCD and CMOS-based cameras to correct for sensor artifacts, lens artifacts, and illumination artifacts (shading). The purpose of flat field correction is to ensure image uniformity regardless of exposure.
Okay so we just talked about how you may not have to make a choice between a CCD or CMOS image sensor. However, since that is not the case at the moment (examples expected in 2015) what to do if you need to make an industrial camera selection now?
The latest requirements for 3D metrology and inspection in the semiconductor industry require high resolution and fast frame rate cameras. For these applications, CMOS-based cameras are required, with the trade-off of lower dynamic range and less sensitivity compared to CCD-based cameras. CMOS image sensors continue to get dramatically better fueled by the extensive resources and R&D in the consumer market, but what if it was possible to have no trade-offs?
There are many amazing new products and technologies unveiled and discussed at this week’s Photonics West Show. We are impressed at how many industries from agriculture to medicine are advanced by photonics.
A multiple camera (multi-camera) based vision system can provide a bigger field of view, faster throughput, greater detailed inspection or more measurement information, and possibly all combined for metrology and inspection equipment.
CoaXPress version 1.1 was released in April of 2013 and now products based on this version are available.
The new Truesense Imaging (TSI) CCD sensors: the 1080p KAI-02170 Interline CCD image sensor, and the 4 megapixel KAI-04070 Interline CCD image sensor, were designed to provide superior image quality for the most demanding imaging applications. The Adimec OPAL-2070 and OPAL-4070 CCD machine vision cameras are the latest members of the OPAL series designed around these sensors. The larger pixel size of the image sensor enables gains in light sensitivity, dynamic range, smear rejection, and blooming suppression for applications with difficult image capture conditions or precise image quality requirements.
There are always small changes (at no additional product cost) that can be made to increase the performance of your machine vision camera and thus to your overall inspection or metrology system. Binning is one example. There has been a trend with latest generation image sensors to increase resolution while also reducing the pixel size at the expense of some other performance parameters. If you do not need all of the resolution provided, but require better signal to noise ratio for instance, then binning is an easy solution. Here we will discuss binning with CCD cameras (interline transfer image sensor technology). For more information on binning with CMOS cameras, please see a previous post.
There are many considerations as you decide on the best machine camera whether it is for an upgrade to an existing system or for a new project. Here are some recent blog posts to help you with the process:
Each year there are exciting advances in what is possible with a machine vision camera. These cameras are going way beyond industrial manufacturing into defense surveillance systems, robotic surgery, intelligent traffic systems, border security, health monitoring, and more. In 2013, we discussed many of these new applications in detail on our blog. Here are a few:
