Double-rate technology
Recent advancements in CMOS image sensors has made them a mature technology
with more developing potential than their CCD counterparts.
State-of-the-art CMOS imagers with active pixels are unsurpassed in terms
of their extraordinarily high-dynamic properties, their antiblooming resistance
and their readout speeds (up to 60 MHz per output channel). Further key
advantages are the ability to assess only parts of an image (ROI) and
of integrating functionality on the chip. Their ability to manage high
frame rates take CMOS imagers to the forefront of high-speed image capture
and image analysis. The combination of CMOS technology's many advantages
can drastically reduce the overall implementation cost of a vision system.
Recognising the requirements for applications needing fast motion-analysis,
Photonfocus, uses a proprietory modulation algorithm to double the maximum
frame rate and incorporates a double bandwidth for data transmission via
the standardised GigE interface
The Double Rate camera technology, which is based on
the standard implementation of the GigE interface and standard GigE-Vision
and GenICam software protocols, enables standard tools and libraries to
be used in high-speed applications. It overcomes the drawback of link
aggregation and enables frame rates of 577 fps at VGA resolution and 204
fps at 960 x 960 pixels to be achieved.
An added advantage of Photonfocus' technology is the camera's capacity
to save unmodified image formats and using half the storage space compared
with standard solutions.
Applications
Suitable for single or multiple camera setups,
the camera is perfect for deployment in areas such as bionic, sports or
bio-mechanical analysis and process failure analysis; eg burst or fracture
of tools, failure of handling systems or break-down of packaging systems
- all these applications needing the high frame rates provided by CMOS
technology while the combination of the GigE interface and the standard
software protocol, GeniCam, eliminates the complications of cameras adopting
the Link aggregation solutions.
In image analysis applications, near-infra-red markers are often used
to enable data capturing and the high quantum efficiency of the sensor
used in the DR1-D1312-200-GB-8 is the key to the good image quality produced
by the camera. For applications working on higher wave lengths (e.g. in
the near infrared area) a specific NIR sensor can be used in the same
camera type.
