In this paper, we introduce a novel approach utilizing a 5–layer all–optical D2NN constructed with photo–induced liquid crystal alignment technology to create LC–based tunable phase retarders, experimentally achieving a classification accuracy of 89% with 500 random hand-written digits from the test MNIST dataset.
