Tips: Briefly introduce the working principle of laser tachometer

A laser tachometer is a non-contact device used to measure the rotational speed (RPM) of a surface or object. Its working principle involves the following key steps:

• Laser Emission: The tachometer emits a coherent laser beam towards the rotating object.
• Reflection: When the laser beam strikes the surface of the object, it reflects to the tachometer. The surface of the object should ideally be rough or have a reflective marking to enhance the reflection.
• Detection: The tachometer contains a photodetector that senses the reflected laser beam.
• Frequency Measurement: As the object rotates, the laser beam hits different points on the surface. The tachometer measures the time interval between successive reflections, which is related to the speed of rotation.
• Output Calculation: The device calculates the rotational speed in RPM based on the frequency of the reflected signals and displays the result.

Laser tachometers are valued for their accuracy, non-contact measurement, and ability to work with a variety of surfaces and speeds, making them ideal for many industrial applications.
