What are the common problems of laser rangefinder?
Frequently asked questions about handheld laser rangefinder:
1.What is the measurement range of the laser rangefinder?
The shortest interval is 0.2m and the maximum interval is 200m.Depending on the spacing of the reflector surface, the measurement interval of 200m will be satisfactory by fitting various accessories such as reflectors and telescopes.
2. Does the laser rangefinder need to be measured by reflection prism?
No reflection prisms are required for fast, contactless ranging of the natural appearance of any flat or convex surface.
Note: it is difficult to confirm the target surface of infrared transparent objects by test glass and water, please use as appropriate!
3. What is the measurement accuracy of the laser rangefinder?
Can be up to + / - 1.5 mm
4. Is the operation of laser rangefinder very complicated?
Very brief, perfect menu-based use.Simply press the measurement button and the result will be displayed on the screen.
5. Does the measurement take a long time?
Measuring time 0.5-4 seconds, very fast.
6. What power source is used for the laser rangefinder?How long does it last?
It only needs 2 5 dry batteries or 9V square batteries.Each battery can be measured thousands to tens of thousands of times.
7. Can laser rangefinder cause damage to human body?
The laser chooses the level 2 laser, will not have any damage to the human skin, but cannot look directly at the laser with the eye or with the optical device.
8. How to measure at a distance interval or outdoors when the laser beam spot cannot be clearly seen?
Rock K3 with anti-interference measurement, Pro S3 series, Rock X3 and i1 with green light indicator are selected.Be able to aim at the target accurately.
9. Does the laser rangefinder store data?
Generally, there is no storage function, some can store the final 20 groups of test data.
10. Are there any other special functions of the laser rangefinder?
Instrument has the function of continuous measurement, with Pythagorean theorem, can measure height, with the maximum value, minimum value measurement, can easily get the most accurate interval, with the function of delayed punctuality measurement.
11. Will the laser rangefinder be bulky and inconvenient to use?
The latest models weigh as little as 300 gigabytes (including batteries), making them even smaller and easier to carry than our phones.
How to ensure the precision of laser rangefinder?
Today, laser range finders of a wide range of functions, but from the operation mode (or operation principle) can be seen only two, namely: pulse laser ranging and continuous wave laser ranging.The principles and characteristics of the two rangefinders are described below:
The principle of pulsed laser ranging is that a series of very narrow light pulses (pulse width is less than 50ns) are transmitted to the policy by pulsed laser, the light reaches the policy surface and is partially reflected, and the interval between the rangefinder and the policy can be calculated by measuring the moment when the light pulse is transmitted to the receiver. Assuming the measured interval is h, the reciprocating moment of light pulse is t, and the propagation velocity of light in the air is c, then: h=ct/2
Pulsed laser rangefinders emit very strong lasers.The range finding ability is strong, even for non-cooperative policy, the maximum range can reach more than 30000m.Its ranging accuracy is generally 5 meters, the highest up to 0.15m.Pulsed laser rangefinders can be used for ranging from military to non-cooperative ranges, to climate measurements of visibility and cloud heights, and to fine interval measurements of satellites.
Successive wave laser rangefinder usually adopt ranging based on the phase method and its principle is to approach first launched a beam of laser beam through modulation of successive waves, after arriving at the policy on the surface of the beam is reflected, after the launch of the modulation measurement of the phase difference between the laser beam with the receiver to receive the echo can be concluded that policy and the gap between the rangefinder.
