Abstract:
A method of and an apparatus for use in determining one or more alignment properties of an illumination beam of radiation emitted by a radiation source are provided. The illumination beam is for irradiating a target area on a substrate in a metrology apparatus. The method comprises: (a) obtaining a first set of intensity data; (b) obtaining a second set of intensity data; (c) processing said first and second sets of intensity data to determine said one or more alignment properties of said illumination beam of radiation; wherein said processing involves comparing said first and second sets of intensity data to calculate a value which is indicative of a translation of said illumination beam of radiation.

Claim (Index 17):
The method of  claim 16 , wherein the second set of intensity data represents the projection of the second beam of radiation onto the second pixelated sensor and steps (a) and (b) are performed simultaneously or are performed sequentially in time.
