Abstract: Self-mixing laser Doppler velocimeter based on a two beam geometry scheme is investigated using a single-frequency Yb:Er-doped phosphate glass laser. The geometry allows the observation of a ...

The V63 Laser Carbine was introduced to Fallout 76 as part of the Milepost Zero update. Here's how players can get it.

Abstract: We often rely on the emitted harmonic component for the localization of a non-cooperative source, through the Doppler shifted frequencies (DSFs) resulting from the relative motion with the ...

Doppler velocity images are now available on the web for a number of Doppler weather radars around Australia. This section gives some guidelines on how to interpret the images. It should be stated at ...

The Doppler Effect is a fundamental principle in physics that describes the change in frequency of a wave – such as sound or light – as perceived by an observer moving relative to the source of the ...

Most radars can measure reflectivity but you need a Doppler radar to measure velocity. Some 40 years earlier in 1842 the Austrian physicist Christian Doppler had discovered what is now called the ...
