Hello All,

 

I am trying to removing the background and normalizing the image data. I have an image which I attached here. 

All I want as end result of normalized image with no background. 

At last  I want to check the beam profile before and after.

 

Is anybody previously worked on it?

Any VI?

Any help would be appreciate.

 

Thanks in Advance

Yes. kind of . Do you have a VI for this?

Other thing I am looking for calculating beam profile. 1/e^2 measurement of beam profile. 

Here is the example I attahed

My example uses the second technique (subtracting a constant at IMAQ Subtract). Where are you getting these requirements from?

Also, it's nice if you let us know where you've cross posted this so we don't duplicate efforts

Try right clicking, saving the image to disk, and then drag the saved file from explorer to your block diagram. The snippet is in 2017 so if you need an earlier version you might have to ask someone to down convert it or... there's not that many blocks there, maybe you can try and recreate it.

It works properly. 

Thank you so much.

 

Other thing I want to ask you regarding auto exposure. Did you have any idea If we want to perform auto exposure of the camera how can we perform ?
