A wide variety of laser doppler anemometer options are available to you, A Laser Doppler Velocimeter (LDV), also known as a Laser Doppler Anemometer (LDA), is a type of interferometer that measures the velocity of objects using laser light. The objects can be microscopic particles in a fluid or solid surfaces—the concept is even used in some high-end laser mice. A period timing device suitable for processing laser Doppler anemometer signals has been described here. The important features of this instrument are: it is inexpensive, simple to operate, and A laser Doppler anemometer includes at least a first and second laser source, an optical system for directing laser beams from the sources to a specific region of a fluid flow containing particles in order to produce a virtual interference fringe pattern and at least one photodetecter positioned for receiving the scattered light from the flowing fluid. In this Laser Doppler Anemometer educational kit LDA CA-1350 Laser beams interact with small distortions on a rotating disc.

Alat yang satu ini memanfaatkan sinar laser yang terbagi menjadi 2 buah balok. Salah satu dari balik tersebut mengelilingi anemometer. Partikel yang mengalir dengan molekul udara akan melewati dan mendekat ke arah balok yang mencerminkan / backscatter, lalu lampu kembali ke arah detector. Kemudian diukur oleh sinar laser. Measurements of flow pattern in a 150 mm i.d.

Laser Doppler surface velocimetry is optical length and speed measurement according to the principle of the laser Doppler effect, evaluating back-scattered Laser Doppler vibrometry (LDV) is currently the method that offers the best displacement and velocity resolution and is used in many fields of basic science. Use the Anemometer to measure wind speed in a variety of experiments. Hold the sensor in your hand to measure wind speed in dynamic environments or use The PV-01 from Canon is a compact, high-precision laser Doppler velocimeter with S-100 and S-150Z/200 optical sensors that can measure the velocity and LaserFlow® Non-contact Velocity Sensor.
