Abstract
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 Ato Adefined by circumferences with p radiuses rto r(p is an even number, r>r> . . . >r>r, and r−r>r−r> . . . >r−r>r−r>r) around a predetermined position are set in order from an inner side, a region A(m is an even number not less than 0 and not more than p) is a light transmission region, and a region A(n is an odd number not less than 0 and not more than p) is a light shielding region.
