Laser range finder manufacturers tell you about problems with range finders
Now using a laser rangefinder could easily measure distance, don't need you to take circle feet to calculate, we measured the distance is a good helper, henan zhengzhou manufacturer of laser rangefinder remind laser rangefinder various brand can according to your budget and actual use, to determine the laser range finder, domestic price cheap, but the performance stability is poorer than a imports, imports of laser range finder are relatively mature, but the price is much higher than domestic, and after a domestic is complicated. So what problems do we encounter in using laser rangefinder? Zhengzhou Defy laser rangefinder manufacturer listed several common problems.
What is the principle of using infrared ranging or laser ranging?
The ranging principle can be basically reduced to measuring the time required for light to travel to and from the target, and then calculate the distance D through the light speed c =299792458m/s and atmospheric refraction coefficient n.Because it is difficult to measure time directly, the phase of continuous wave is usually measured.Of course, there are impulse rangefinders, typically the WILD di-3000.It should be noted that phase measurement is not to measure the infrared or laser phase, but measure the modulation of the signal phase above the infrared or laser.The construction industry has a hand-held laser rangefinder for measuring houses that works in the same way.
Must the plane of the object be perpendicular to the light ray?
Usually precise ranging needs total reflection prism, and the house measurement of the rangefinder, the direct reflection of the wall to measure, mainly because the distance is relatively close, light reflected back the signal strength is large enough.With this you can know, must be vertical, otherwise the return signal is too weak to get the exact distance.
Is it ok if the measured object plane is diffuse reflection?
It is usually possible to use thin plastic sheets as reflective surfaces in practical projects to solve the serious problem of diffuse reflection.
Ultrasonic ranging and laser ranging differences?
Ultrasonic ranging accuracy is relatively low, now rarely used.The accuracy of laser rangefinder can reach 1 mm, suitable for all kinds of high precision measurement purposes.
What are the advantages of laser golf rangefinder?
As the name suggests, laser golf rangefinder is a primary for the golf course of an auxiliary machine, but because of its excellent advantage function, make it in practice is not only used in the golf course, but for the whole shopping mall.According to the golf rangefinder merchants query flash, laser golf rangefinder in the whole shopping mall has been an excellent sense of customer understanding.Here's a look at the advantages of laser golf rangefinders after all.
The laser golf rangefinder ends the driveless part of the structure, and through the original laser optical planning makes the laser golf rangefinder in maintaining high brightness of parallel transmission light, the end of the laser scanning method is completely different from the driveless part of the structure, and then useful to reduce the operating pressure caused by the drive. In addition, it also conforms to the environmental tolerance standard IP67, and the standard air scavenging component can also be useful to avoid the sensor head front contamination, ending the environmental tolerance planning for a long period of stable operation in various environments.Because the outer aluminum body and the inner optical unit are independent, the outer body can maintain the internal optical unit after absorbing the impact and temperature changes, making it have strong resistance function in any environment.
Golf laser range finders outside side chooses is made by metal alloy technology, can carry on the work in any situation and environment, make it has high speed and high precision two efficient function, and can carry on the red outer side sight equipment, makes the laser can be visible to the naked eye can see, the more beneficial to customers friends to investigate the intuitive approach, reduce unnecessary cognitive mistakes, arrived in extremely efficient targeting.
Because the laser golf rangefinder has a more ambitious environmental tolerance planning, so that it can minimize the use of time to reduce the wear caused by external objects, in the maximum maintenance of the laser golf rangefinder use life. And because of its concise appearance, no messy planning, the end of completely no drive structure, can be useful to avoid the prism and motor due to long-term use of deterioration, significantly reduce maintenance costs.Then make later need not too much maintenance, can be said to have reached the maintenance free stage, more convenient for customers to use friends.
The above three points are the advantages of laser golf rangefinder.Although the laser golf rangefinder structure is attributed to the very simple mechanical equipment, but it has these advantages are similar products in the market can not reach.And with customer friends on the range finder requirements of the continuous progress and range finder experts continue to develop, making the advantages of laser golf range finder more significant.
