Abstract
Systems and methods are provided or use with a light source which generates a light beam. These systems may include a detector which detects light beam information and which determines whether multiple modes are present in the light beam so that the light source may be adjusted. These systems may further include a beam splitting device, such as an optical wedge, to provide two sample beams that intersect to provide a fringe pattern. The detector may then detect this fringe pattern and compute a visibility value that may be used to determine whether multiple modes are present.
