Overview

• Researchers at Kobe University have developed a single-pixel camera capable of recording three-dimensional videos, even through scattering materials like tissue.
• The system uses a high-speed digital micromirror device operating at 22 kHz to project holographic patterns, significantly enhancing imaging speed.
• Proof-of-concept experiments, published in *Optics Express*, demonstrated successful 3D imaging through a mouse skull at a frame rate of just over 1 fps.
• Sparse sampling techniques and deep-learning optimizations are being explored to increase frame rates to 30 Hz for real-time applications.
• The technology shows promise for minimally invasive, real-time 3D observation in biomedical fields, including diagnostics and microscopy.
