Abstract
An A4-sized parallel phase-shifting digital holography system was constructed and
experimentally demonstrated. Parallel phase-shifting digital holography is a technique being
capable of instantaneous recording of three-dimensional (3-D) image of moving object. Aiming at a
3-D motion picture measurement of moving object system that can be carried on sites where the
measurement system is needed, we improved a previous portable parallel phase-shifting digital
holography system. The size and weight of the improved portable system are 300 mm
$\times\, $
210 mm
$\,\times \,$
160 mm and 6 kg, respectively. Also, we experimentally recorded a series of
holograms of a moving object and reconstructed motion pictures, which show the same event but are
focused at each depth, from the holograms. Thus, the 3-D motion picture recording and
reconstruction capability of the constructed system were successfully demonstrated. A 3-D motion
picture at 10 frames/s was obtained by the system.
