In Journal of Applied Physics, researchers describe an acoustic metasurface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation. The coupling between two resonators led to two resonance frequencies, and more resonant frequencies meant the device was able to absorb more sound. At the success of two coupled resonators, the researchers added more, until their device resembled a square sheet of punctured pingpong balls, multiplying the number of resonant frequencies that could be absorbed.

An ideal holographic 3D display should offer large viewing angle, full color, and low speckle noise. A new holographic 3D display system with a large viewing angle of 73.4° has been proposed. The system uses spatial light modulators (SLMs) and liquid crystal grating to achieve maximum diffraction modulation, which allows for a larger hologram size and a wider viewing angle. The proposed system has potential applications in education, culture, and entertainment.
Quantitative phase imaging (QPI) is a label-free computational technique frequently used for imaging cells and tissue samples while facing challenges when diffusive media obstruct the optical path.
