This sensor can measure target velocity. The working principle is based on the self-mixing effect that occurs in a semiconductor laser diode when the emitted radiation is back reflected toward the cavity and then re-introduced inside. The target velocity is calculated measuring the frequency of ...
By replacing the two detectors of a standard phase-Doppler anemometer (PDA) with a charge coupled device (CCD) line scan sensor, the scattered light can be measured not only with high temporal but also with improved spatial resolution. Thereby, the quantity to be measured by PDA, the phas...

The LDA equipment is a powerful tool for the measurement of flow velocity and velocity fluctuation, as well as the local concentration of particles or droplets transported in the airflow. This section introduces the measurement principle, optical path models, commonly used instruments, and ...
Micro-Doppler frequency varies with the velocity of a moving target so that each movement has its unique micro-Doppler signatures, which can be used for activity recognition. Conventional Doppler-based activity recognition requires well-designed features from micro-Doppler spectrogram to support an ...
