Frequency-modulated continuous-wave lidar is evaluated for range finding, velocimetry, and laser anemometry. An original signal processing and waveform calibration for range finding leads to a reduction of computational effort while preserving capability for long-range measurement. Multiple target distance measurement is also demonstrated.

For range finding, the aim of this signal processing is to extend lidar range and reduce ambiguities. Moreover, the effect of moderate atmospheric turbulence on lidar efficiency is analyzed for infinite and finite targets, taking into account wind-induced bistatism.

- Nanometre-scale features on insect surfaces give them unique survival properties, such as low light reflectance and oil repellency.
- The study explores how these natural textures can be mimicked in materials to enhance antifogging capabilities.
- Using nanocones significantly improves hydrophobic properties, making surfaces nearly completely antifogging and allowing tiny water droplets to roll off easily.
