Claim:
1. A method calibrating a beam shaping module including a first and a second optical modules sequentially interacting with a light beam; the method comprising carrying out the following steps: i. measuring a first intensity distribution of said light beam after its interaction with said first optical module, at a certain optical distance downstream from said first optical module, and utilizing said first intensity distribution to determine a lateral misalignment of said first optical module, thereby enabling calibration of a lateral position of the first optical module; and ii. when said first optical module is in said lateral aligned position, measuring a second intensity distribution of said light beam at a certain location downstream from said second optical module, and utilizing said second intensity distribution to determine a lateral misalignment of said second optical module, thereby enabling calibration of a lateral position of the second optical module.
