Figure 5
2D experimental diffraction pattern and profiles along the horizontal and vertical directions. Calculated profiles are also shown. The black line is the calculated Gaussian beam = 256 µm of the Fresnel diffraction pattern with approximately 75% coherence. (a) Mask 1: 164 µm × 98 µm, Fh = 6.6, Fv = 2.3. (b) Mask 2: 270 µm × 120 µm, Fh = 17.8, Fv = 3.5. |
