PXI frame grabber provides high data throughput


The NI PXIe-1435 Camera Link frame grabber from National Instruments can be used to integrate high-speed and high-resolution imaging into a PXI systems.

The PXIe-1435 acquires from all Camera Link camera configurations, including 10-tap extended-full, with up to 850 MB/s of throughput. Engineers can power cameras through Power over Camera Link (PoCL)-enabled cables, eliminating the need for additional wires in deployment environments.

The frame grabber also offers 512 MB of DDR2 onboard acquisition memory for added reliability in transferring large images without fear of data overflow. Onboard digital I/O includes four bidirectional transistor-transistor logic, two opto-isolated inputs and one quadrature encoder for triggering and communicating inspection results with automation devices.

The frame grabber incorporates the synchronization, timing, data streaming and processing capabilities of the PXI Express specification, and supports image processing on complementary field-programmable gate array boards to further boost system performance.

The frame grabber is suitable for line-scan image sensors, which engineers can use for surface inspection of large areas, including finding esthetic and functional defects in solar panels and dead pixels in flat panel displays.

The NI PXIe-1435 frame grabber can be used in industrial applications, such as fault analysis using a stop trigger to record images before and after an event on the factory floor, and medical device applications such as analyzing intricacies in movement and recording stimulus response in objects from heart valves to eye corneas.

Engineers can program the module using NI LabVIEW graphical development software and the NI Vision Development Module, a library of imaging functions. They can also configure it using NI Vision Builder for Automated Inspection software, a stand-alone package for fast development and simple maintenance.
