LabView Beamprofiler ISO 11146 Introduction

Hello Guys,

here i will present you how to create a beamprofiler according to the ISO Standart 11146.
I started to develope such a profiler in LabView and will show you the individual steps.

A Laser-Beam-Profiler is a tool to measure the characteristic parameter of a laserbeam, such as beamradius, ellipticity and M². Measuring and optimizing a laserbeam gets more and more important in application like lithography or laser welding.

A typical beamprofiler looks like this:

To measure such a beam you can use a knife-edge profiler, a slit profiler or recently more common a ccd sensor.
