Diamond Metasurface‐Based Optical Tweezers With Enhanced Robustness

Advanced Science, EarlyView.
Conventional metasurface optical tweezers are hindered by thermal instability from laser heating. This work overcomes this by using diamond metasurfaces, exploiting their low thermo‐optic coefficient and minimal thermal expansion. The platform demonstrates stable particle trapping, translocation, and rotation, enabling robust miniaturized systems for ...

Deep Volumetric Super‐Resolution Imaging in Thick Biological Specimens With Sparse Scanning SIM

Advanced Science, EarlyView.
Sparse scanning structured illumination microscopy (SS‐SIM) extends the axial depth in super‐resolution fluorescence imaging by combining rapid laser scanning, pixel‐addressed intensity modulation, and sCMOS camera detection. SS‐SIM yields 1.6× lateral and 1.7× axial resolution gains over wide‐field microscopy and enables imaging through 300–600 µm ...

Modulating Phase Encoding With Amplitude Compensation for Hologram Reconstruction

IEEE Photonics Journal
In holographic three-dimensional (3D) display, phase-only spatial light modulators (SLMs) can only accept pure phase modulation signals, often leading to amplitude distortion in the reconstructed image and inaccurate object reconstruction.
