Numerical Analysis of Three-Dimensional Object Recognition with Digital Holography

We describe an intrinsic correlation peak of three-dimensional (3D) pattern recognition, which is higher than thatof the two-dimensional (2D) pattern recognition and whose difference can reach up to five orders of magnitudein our numerical simulation. The relationship between the 3D objects and their recognition result is formalizedand the comparison between the 3D and 2D pattern recognitions as well as the former‘s independency of thereconstruction distance is presented. Finally, the augmentation of the 3D pattern recognition sensitivity with theincreasing surface complexity of the 3D object is also demonstrated.
