T. Shakushio and S. Komatsu : Extension of depth of field for iris recognition system by wavefront coded imaging using free-form phase mask, Technical Digest, MOC'09 (Odaiba, Tokyo, 2009), 314-315 (2009). (J-96)

We examined the extension of depth of field (EDOF) for an iris recognition system by wavefront coded imaging using a free-form phase mask (FPM). We found that wavefront coded imaging using the FPM has a better performance than conventional imaging through the experiment on EDOF for the iris recognition system.
