Test for flasing light

[Damien129]

Hi Ben,

With the frequency at a certain rate flashing on and off every half second give or that, is there a way of ensuring that when the camera captures an image that the led has in fact switched off or back on?

For the aqcuisition with the inline processing i can time the FOR loop to execute every 500ms for instance how would i time this in the post processing method? Would it be the configuration of the trigger or timing the execution of the execution or how would i achieve this?

Regards,

Damien

Hi Damien,

Using inline in this case is fine, I had previously thought that you mentioned that the LED would flash 50 times a second. As long as the loop takes less than half the LED flash time, you should be able to capture at least one change when the LED is flashing. From here the comparison I would make would be to two arrays of either all false, or all true. This way if any of the acquired images have differences the comparison would pick them up.

I hope that helps, and apologies for the confusion.
