Abstract

This laser beam measurement system comprises a laser source configured to emit laser radiation towards a target and a detector (2) arranged to receive said reflected laser radiation (8) from the target, which is equipped with a pixel array (10) and configured to measure the location of said reflected laser radiation (8) on the pixel array (10). The laser beam measurement system further comprises a diapometer (4) equipped with first and second optical components (4A, 4B) arranged along the optical path of said reflected laser radiation (8) and which are free to rotate independently of each other about an optical axis (A) of the laser beam measurement system. The first and second optical components (4A, 4B) are each equipped with a metasurface (12A, 12B) configured to deflect said reflected laser radiation at first and second deflection angles (α1, α2), respectively. (See Figure 2 for abbreviations.)
