New Camera Does Realtime Holographic Capture, No Coherent Light Required
1 min read
Summary
A team of researchers from the University of Cambridge and the UK’s Quantum Continuous Generation (QCG) group have developed a holographic camera that can capture and reconstruct a 3D scene in under 30 milliseconds, using incoherent light.
The camera splits into two parts: an electrically driven liquid lens system that captures a focal stack in 15 ms, and a deep-learning neural network that processes the data in 13 ms to generate a high-fidelity RGB hologram.
Holography captures a scene’s wavefront information, including light direction and interference patterns, enabling the optical reconstruction of a scene from different perspectives and with different focuses.
The team hopes the technology will democratise development and experimentation with holography, which has until now been a complex and specialised field.
