How do you make a laser measuring device


1. the principle of infrared distance measurement or laser distance measurement

The ranging principle can be basically reduced to the time required to measure the light to and from the target, and then the distance D can be calculated by the light speed c =299792458m/s and the atmospheric refractive index n. Because it is difficult to measure the time directly, it is usually to measure the phase of continuous wave, which is called phase measuring distance meter. Of course, there are also pulse rangefinders.

It should be noted that phase measurement is not to measure the phase of the infrared or laser, but to measure the signal phase modulated on the infrared or laser. There is a hand-held laser rangefinder in the construction industry, which is used for house measurement, and its working principle is the same.

2. the plane of the measured object must be perpendicular to the light

Generally, precision ranging requires the cooperation of total reflection prism, while the range finder used for house measurement is directly measured by the reflection of smooth wall surface, mainly because the distance is relatively close, and the signal intensity reflected by the light is large enough. From this, we can know that it must be vertical, otherwise the return signal is too weak to get an accurate distance.


3. the object plane can be measured as diffuse reflection

It is usually possible. In practical projects, thin plastic plates will be used as reflecting surfaces to solve the problem of serious diffuse reflection.


4. entertainment products of pulse laser rangefinder can achieve display accuracy of 1m, measurement accuracy of ± 1m, display accuracy of 0.1M and measurement accuracy of ± 0.15m for measurement products.


5. the precision of phase laser rangefinder can reach 1mm, which is suitable for various high-precision measurement purposes.
