Choosing the best camera sensor technology for imaging needs

A wide range of camera technologies covering a host of industrial and scientific imaging applications will be shown by STEMMER IMAGING at Vision UK Photonex. Cameras with the latest Sony CMOS sensors with high light sensitivity and dynamic range can be seen alongside high resolution high speed cameras, Short Wave IR cameras and a dual CCD camera for simultaneous imaging of visible and NIR light.  

The new Sony IMX174 2.3 Mpixel CMOS sensor from Sony offers performance not previously achievable with CMOS sensors in terms of light sensitivity, dynamic range and pattern noise, as well as delivering on colour reproduction. These sensors can be seen in action in the latest cameras from IDS and AVT.

High resolution, high-speed imaging will be demonstrated using a Falcon 2 camera from Teledyne DALSA linked to a frame grabber from Silicon Software which provides extended FPGA image processing using VisualApplets. This will be configured for image pre-processing to manage the high data rate from the camera.

A dual CCD multispectral camera from JAI will also be on show which allows simultaneous visible and NIR imaging of exactly the same field of view. These cameras feature two CCD sensors looking through a single lens. This powerful arrangement allows the full benefits of imaging using NIR radiation to be realised enabling features below the surface of an object to be viewed, which may reveal otherwise unobservable defects. 

Short Wave IR cameras offer the ability to image both reflected IR and IR emitted at higher temperatures (300°C -800 °C). SWIR imaging will be demonstrated with cameras from AVT and Xenics which feature InGaAs sensors stabilized with TEC1 peltier cooling.
