Description:
We present a handheld holographic video camera that captures full-color, complex holographic video under ordinary lighting conditions. By adopting the self-interference incoherent holography principle, it eliminates the need for a laser light source, which is typically required for hologram recording, by integrating a geometric phase lens and a polarization image sensor, the system records complex-valued holograms in real time, without bias and twin image noises. Its centimeter-scale co-axial design enables truly mobile, handheld operation, while digital refocusing at arbitrary depths is achieved through numerical propagation with no prior knowledge. A video-based super-resolution algorithm further enhances the hologram’s quality, preserving digital refocusing capabilities. The demonstration highlights the feasibility of everyday holographic content acquisition, bridging the gap between the laboratory and real-world applications.
