摘要

Subject of study. A device for recording color volume holograms (with Bragg gratings) is presented. Its scheme is based on the joint object channel for three redgreenblue colors. Main results. A scheme with sequential exposure is proposed, which makes it possible to use one spatial light modulator. The scheme is more compact and more resistant to vibration and air currents. A scheme for recording synthesized holograms in sequential exposure mode with vertical position of the recording medium is presented. It ensures the quality and volume properties of the reconstructed three-dimensional images, which are sufficient for continuity of their perception. The possibility of using white light for reconstruction of the volume holographic image recorded using the proposed scheme is confirmed. Practical significance. The scheme for recording color volume holograms presented in this study makes it possible to record holograms with full parallax by sequential exposure of different distributions for each color using continuous lasers with acoustic-optic modulation.
