ROBUST CONJUGATED-SYMMETRIC OPTICAL APPARATUS AND DESIGN METHOD THEREOF

摘要

A robust conjugate symmetric optical apparatus is disclosed. The robust conjugate symmetric optical apparatus comprises a first optical cell set and a second optical cell set. The first optical cell set includes a first plurality of cells, each of which includes a first left half cell and a first right half cell, and the respective first right half cell and the corresponding first left half cells form a first symmetric structure therebetween. The second optical cell set includes a second plurality of cells, each of which includes a second left half cell and a second right half cell, and the respective second right half cell and the corresponding second left half cells form a second symmetric structure therebetween, wherein each of the first left half cells of the first optical cell set and each of the second right half cells of the second optical cell set have the same structure; and each of the first right half cells of the first optical cell set and each of the second left half cells of the second optical cell set have the same structure.
