Embodiment 2
[0056] The beam target field amplitude that needs to be obtained is a sinusoidal distribution, and the width of the curve is 2 pixels, that is
[0057] A = 1 ( 50 sin ( n - 256.5 ) - 1 ≤ n 50 sin ( n - 256.5 ) + 1,128 m ...
Embodiment 3
[0063] The beam target field amplitude that needs to be obtained is six straight lines, and the width of each straight line is two pixels, namely
