allPixa line scan camera
Chromasens, the image processing specialist from Constance, Germany, has added the allPixa model to its high-performance industrial colour line scan camera portfolio.
The model features a line frequency of 96kHz, a 2.5-fold increase in comparison with its predecessor. In order to be able to transmit the generated data quantities in real time, the camera is also equipped with an interface that allows maximum transfer rates of 450MB/s. This means that the objects being examined can either be inspected at the previous image quality, but considerably quicker, or at the same speed as before and in more detail.
The application fields for the camera range from document scanners and print quality inspection to sorting systems and quantity control. The camera is particularly suited to surface inspection of semiconductors and displays, for example, or in the inspection of natural and artificial materials such as wood, paper and food.
Trilinear CCD colour line scan sensors form the basis for the image capturing in the allPixa models. The platform for electronic image processing is based on state-of-the-art chip technology from the US company Xilinx, a supplier of FPGAs.
The colour line scan camera is available in four resolutions: 1,024, 2,048, 4,096 and 7,300 pixels. The resolution of the A/D conversion is 14-bit.
With its diverse application possibilities, the camera system offers the user a high colour consistency. Pioneering technologies, such as continuous white balancing during recording provides consistently excellent colour quality. This creates a solid basis for colour recognition solutions and stable colour management.
In addition, pixel-based correction ensures different sensitivities of the colour pixels and illumination procedure are balanced out. An integrated, digital shutter means that recording continues without information gaps when different track speeds are employed. Changes in the direction of scanning can be monitored independently. The sub-pixel registration error correction is automatically adjusted when the direction is changed. Further customer-specific image processing functions are available on request.
The housing, which is suitable for industrial environments, offers a wide range of mounting possibilities. The camera is also equipped with a flexible programmable, digital I/O interface for different signal types (LVDS, LVTTL, RS422), with which, alongside trigger input and output, further control signals are also possible.
