ABSTRACT:
A phase modulation element according to the present invention has a first area having a first phase value based on a phase modulation unit having a predetermined size and a second area having a second phase value based on the phase modulation unit having the predetermined size, and each phase distribution is defined by a change in area shares of the first area and the second area depending on each position.
