Toward label-free ultra-high-resolution imaging via wavevector resonance

Label-free spatial-frequency-shift (SFS) super-resolution imaging enables nanoscale visualization but fundamentally suffers from a severe trade-off between ultra-high resolution and high signal-to-noise ratio (SNR) when utilizing high-wavevector illumination. To overcome this limitation, recent advancements have introd...

All-Optical Code-Division Multiple Access LiDAR for Large Nonambiguous Range and High Point Acquisition Rate via Time-Stretching

Light detection and ranging (LiDAR) have become a key enabling technology for autonomous driving and intelligent manufacturing. Conventional pulsed time-of-flight LiDAR suffers from an inherent trade-off between point acquisition rate (PAR) and nonambiguous range, which cannot satisfy the demands of long-distance hig...
