Line acquisition is automatically resumed when forward motion is resumed at the position where acquisition was interrupted.

– The rate converter enables the camera to acquire lines at any programmable resolution below or above the resolution of the motion encoder.

This provides designers with an amazing degree of freedom in the application development process.

This provides designers with amazing freedom and flexibility in the application development process.

– The rate splitter allows the camera to acquire images at a resolution higher or lower than that of the motion encoder,

and is implemented by splitting the encoder input signal using a programmable integer multiple.

input signal using a programmable integer multiplier.

When activated, this feature records metadata beside image data. Line metadata are captured every acquired image line.

Line-scan Metadata insertion

Buffer metadata are only captured when the first image line of a buffer is acquired.

The metadata are composed with a configurable set of general purpose event counters, quadrature encoder

The metadata are composed with a configurable set of general purpose event counters, quadrature encoder position counters and/or I/O line status.

This feature allows line-scan applications to correlate image data with system events including motion encoder positions.

Line Scan Trigger Capability

– The Coaxlink image acquisition card controls the camera scan rate based on signals received from the motion encoder.

If the part is moving faster, the camera’s acquisition line rate will increase.

If the part is moving slower, the camera’s acquisition line rate decreases.

– The Coaxlink board interprets the A/B signals from the Quadrature Motion Encoder to know in which direction (forward or backward) the part is moving.

– The Coaxlink card can also be commanded to acquire laser lines when the object is moving only forwards or only backwards.

– When a backward movement is detected, the function called ‘Backward movement cancellation’ stops the acquisition.

Line acquisition is automatically resumed when forward motion is resumed at the position where acquisition was interrupted.

This provides designers with an amazing degree of freedom in the application development process.

input signal using a programmable integer multiplier.

Area Scan Trigger Function

– Triggers are used to initiate acquisition when a part is in place. Hardware triggers come from Coaxlink’s I/O lines.

Software triggers are from the application.

– Controllable delay triggers to control the point at which image acquisition is delayed.

– Trigger extraction feature allows certain triggers to be skipped.

– Camera exposure control allows the application to control the exposure time of the camera.

– When the system starts to acquire images, the Coaxlink capture card generates a signal at

an appropriate point in time to control the lighting equipment connected to the output.

Line Scan Trigger Capability

Coaxlink supports both continuous roll scanning (to inspect infinite, continuously moving surfaces without losing lines)

and discrete target scanning (to capture images of targets moving in front of the camera).

(to capture images of targets moving in front of the camera).

– Triggers are used to initiate acquisition when the part is in position. 

Hardware triggers are from the motherboard I/O lines. Software triggers come from the application.

– Once initiated, the acquisition will continue indefinitely (for rolling the network):

– Continue indefinitely (for rolled-net monitoring applications)

– continue for a programmable number of lines (to acquire a target image of known length)

– continue until an end trigger signal is received (to acquire variable length target images)

– Controllable delay trigger to delay the start of acquisition by a programmable number of lines.

What are the jitter and latency of CoaXPress-over-Fiber? How do they compare to “traditional” CoaXPress?

CoaXPress-over-Fiber is based on the CoaXPress protocol and it exhibits the same high performance as CoaXPress in terms of jitter and latency.

In addition, as CoaXPress-over-Fiber supports higher transmission speed compared to CoaXPress, the jitter and latency will be further improved in these versions.
