Research Abstract |
We have developed a holographic video camera using a high-power pulsed laser for real-time recording of complex-amplitude holograms. We have also developed a real-time 3-D display system by connecting the holographic video camera to our holographic display system. We have demonstrated real-time recording and reconstruction of moving 3-D images under room lighting. It is possible to record holograms under daylight using a high-power pulsed laser. Calculation time by a usual personal computer is shorter than 30 msec to generate one hologram from a recorded off-axis hologram. Frame rate of this display system is limited by the performance of camera-link image sensor.
