With it's 5 Megapixel image sensor, it can be used in with 5 Megapixel lenses even in ultra-high resolution mode. There is no need for ultra-high resolution lens optics. This is achieved by using a piezo element to shift the sensor by fractions of a pixel both horizontally and vertically in quick succession. This allows a sequence of images to be captured which are then interleaved into the high resolution image on a host PC.
The colour version is particularly versatile. By using the sensor as a standard imager, the field of interest can be quickly located before switching to ultra-high resolution mode. Also, by setting the pixel shift to be one pixel rather than a fraction of a pixel, the camera can operate at the sensor’s 5 Megapixel resolution to provide full RGB output for each pixel without colour fringing. In this mode the camera gives performance equivalent to a 3-CCD device from a single sensor.
The monochrome version offers a frame rate of 0.516fps at a resolution of 125 Megapixels. 1.43fps can be achieved at 45 Megapixels and 15fps at 5 Megapixels. The colour version also has a frame rate of 1.43 fps at 45 Megapixel resolution and 3.12fps in RGB mode.
Data is transferred via CameraLink Base at 8 or 10 Bits. To facilitate easy integration and to generate high-resolution images STEMMER IMAGING provides sample applications with source code for Teledyne DALSA X64-CL and Xcelera-CL PX4 image capture cards, but can advise on the use of other frame grabbers.
STEMMER IMAGING has been one of the leaders in the machine vision market since 1987. It is one of Europe's largest technology providers in this field. In 1997 STEMMER IMAGING presented Common Vision Blox (CVB), a powerful programming library for fast and reliable development and implementation of vision solutions, which has been deployed successfully throughout the world in more than 40,000 imaging applications in various industries.
Teledyne DALSA is one of the largest companies serving the machine vision industry and is unique in that it is vertically integrated; from sensor design and manufacture, through image capture and processing, to software for imaging optimisations and analysis.
