Ommatidia LiDAR
Understanding the Doppler Effect Laser Doppler Vibrometry: Understanding the Doppler Effect. Ommatidia 's laser radar enables simultaneous vibration analysis and high-precision 3D measurement, offering unparalleled accuracy. Laser Doppler Vibrometry (LDV) uses the Doppler effect to measure the velocity and displacement of vibrating surfaces without physical contact. The laser beam reflects off the surface, and the frequency shift in the returned light is directly proportional to the surface 's velocity. This makes LDV...

WaveFarer: Chirp Waveforms and Range-Doppler Chirp waveforms are commonly used in automotive radar and other sensor applications to provide the required information for calculating range and Doppler velocity of objects in a scene from the radar returns. An example is a frequency modulated continuous wave (FMCW) radar, which transmits a sequence of chirps within a frame. The term chirp refers to the adjustment of frequency over a band. Use WaveFarer's scripts and utilities to extract path data from simulations. Once a user has defined... (read more)Browse Modeling and Simulation Software Datasheets for Remcom (USA) -
Endress + Hauser – Sensors & Components
Pressure sensors in ultrasonic doppler flowmeters The application: Ultrasonic Doppler flowmeters are widely used in industrial and environmental applications to reliably monitor the flow rate of fluids containing solid particles, such as wastewater, sludge, or river water. These devices are equipped with integrated ultrasonic sensors that emit and receive sound waves. The measurement principle is based on the Doppler effect: moving particles within the fluid alter the frequency of the reflected sound waves, enabling the calculation of flow...
