Acquire images from multiple synchronized cameras with CoaXPress

Trigger distribution

CoaXPress has a no-jitter, low-latency camera triggering capability. In addition, the C2C-Link functionality of Euresys‘ Coaxlink cards is able to synchronize cameras connected to the same Coaxlink card, to different cards in the same PC and to different cards in distant PCs. Driven by a master Coaxlink frame grabber, all cameras can be synchronized and operate coherently based on the master’s timing. Table 1 shows some examples of configurations.

General Purpose I/Os

Multiple general-purpose inputs and outputs are also available in various hardware flavors (TTL, isolated, differential) on Coaxlink frame grabbers. This allows for local synchronization with various types of sensors such as presence detectors, quadrature encoders and strobe lighting systems. In addition, these signals can be processed internally using rate converters, multipliers, dividers, or programmable delays.

Event Logging Tool

The Memento Event Logging Tool of Euresys is the best way to verify that the cameras are synchronized as intended. Memento records an accurate log of the events related to all cameras, including triggering. It then generates a graphical representation of time-stamped events on a precise timeline, along with context information.
