Black image from Dalsa CL-P1-2048 with 1424

Hi all,I am using Dalsa CL-P1 2048 line scan camera with PCI 1424(LVDS). I checked with MAX and have some problems in acquiring the correct image.

In short I am getting Image only with the following setup in MAX:

1. Integration Type – Total

2. Line rate is less than 10 KHz,

3. Only with Snap & not in Grab operation

4. Only if the acquisition window height is 1.

If any of the above setup is changed then I am getting a black image. Further the image appears only in MAX and I am getting black line/image with Vision builder and LabVIEW.

I have checked for the connections and that’s correct. What could be the problem??
Does the timing of the si
gnals that NI card gives is as per the Dalsa Camera's requirement?
Can we check the signals directly with the scope??
Please reply at the earliest.

Thanks,
Nandhini

Nandhini,

I have seen exactly this behavior before. The problem turned out to be a lack of light since line scan cameras typically require very bright light. Try aiming the camera at a bright light source and see if the image changes.

Brent,
You are right. As you said the problem was insufficient amount of light. We found this when we tested with a DC light source. Line scan cameras require a really very high intensity light.

Thanks,
