Laser Speckles

Hi there!

I have some problems setting the right exposure time while measuring a laser line.

I start of with a specified exposure time and reduce it in a WHILE loop. Yet I don't know exactly how to get the thickness of the laser line (speckles should be removed with this procedure).

Someone there who can help me on this one?

thanx

Hi One,

could you be a little more specific in your question? Do you have an image processing problem (removing speckles) or you'd like some advice on measuring laser beam size?

If you upload some code, maybe we can have a better understanding of what you're trying to do and what's bugging you...
