OPTICAL MASK, AND LIGHT SOURCE DEVICE |
摘要 |
This optical mask is an optical mask which applies spatial intensity modulation to input light in a beam cross-section and outputs a light after being subjected to the modulation, and when regions A0 to Ap defined by circumferences with p radiuses r1 to rp (p is an even number, rp>rp−1> . . . >r2>r1, and rp−rp−1>rp−1−rp−2> . . . >r3−r2>r2−r1>r1) around a predetermined position are set in order from an inner side, a region Am (m is an even number not less than 0 and not more than p) is a light transmission region, and a region An (n is an odd number not less than 0 and not more than p) is a light shielding region.
