Portable parallel phase-shifting digital holography systems

Abstract

We have constructed two portable parallel phase-shifting digital holography systems. One is an A3-sized parallel phase-shifting digital holography system and the other is an A4-sized parallel phase-shifting digital holography system. The size and weight of the A3-sized system are 450 mm (L) × 250 mm (W) × 200 mm (H) and 7kg, respectively. The system was constructed by use of ready-made optical components. To reduce the size and weight of the A3-sized system, the A4-sized system was designed and constructed. The size and weight of the A4-sized system are 300 mm (L) × 210 mm (W) × 160 mm (H) and 6 kg, respectively. The 3D motion picture recording and reconstruction capability of the constructed system were successfully demonstrated at 10 frames/second.
