How weather conditions affect laser rangefinders?
Basically all instruments will be affected by climate and climate, laser rangefinder is no exception, next let me introduce to us what factors will affect the measurement accuracy of laser rangefinder.
We all know that the measurement principle of laser rangefinder is to use the straight line transmission and reflection of light for ranging, but during the measurement process, refraction will occur, and then the measurement error will be formed, but the refractive index can be used for calibration.
When the laser is transmitted in the air, it will be absorbed and scattered by the atmosphere. Generally, the shorter the wavelength is, the stronger the scattering will be, and the weaker the absorption will be.
Because the change of atmospheric conditions makes the refractive index of atmosphere in space straight distribution is not uniform, that is, there is a refractive index straight razor.The path of the light beam transmitted in this space will be a curve, so that its light path is not equal to the verse distance, and there is also the influence of the curvature of the earth when the distance is longer.When the ranging accuracy reaches the micron level and the distance exceeds 10-20 highways, curvature correction should be added.
Temperatures also have an effect on laser range finders, which can be disabled by temperatures above 50 degrees and below 40 degrees.
Detailed explanation of the operation method of laser rangefinder
Laser rangefinder usually USES two methods to measure distance: pulse method and phase method.
The pulse rangefinder works like this: the laser emitted by the rangefinder is reflected from the measured object and then received by the rangefinder, which records the time of the laser's reciprocation.Half the product of the speed of light and the time to return is the distance between the rangefinder and the object being measured.
The accuracy of measuring distance by pulse method is generally about +/-1 meter.Other, the blind area of this kind of rangefinder is about 15 meters.
How to use the rangefinder:
Firstly, arrange theodolite on the station, center and level it, place the main equipment of the rangefinder on the theodolite bracket, lock it with the fixing screw of the coupling, insert the battery into the bottom of the main engine and fasten it.Arrange the reflector at the policy point, center, level, and point the mirror toward the host.
Aim the center of the board with the cross thread of theodolite, and measure the perpendicular Angle alpha.Together, observe and record temperature and barometer readings.To observe the vertical Angle, air temperature and air pressure, the purpose is to correct the tilt, temperature and air pressure of the distance measured by the rangefinder, so as to get the correct horizontal distance.
Press the "PWR" key on the power supply to start the machine, the host will self-check and flash the original set temperature, pressure and prism constant value, and the self-check will flash "good" in the future.
To correct the set value, press "TPC" and enter the temperature, pressure or prism constant (usually through "ENT" key and digital key).In general, just use the same kind of reflector, the prism constant is the same, and the temperature and pressure may be different for each observation, which needs to be set from scratch.
Adjust the hand wheel (or theodolite horizontal fretting screw) and the pitch fretting screw of the main engine by scheduling the altimeter axis, so that the rangefinder telescope can accurately aim at the prism center. n the case of flashing "good", accurate aiming can also be judged according to the sound and motion of the buzzer. The stronger the signal is, the bigger the movement and motion is. The micro-moving rangefinder from left to right makes the maximum movement and motion of the buzzer.
Application field of laser rangefinder
Laser rangefinders are now widely used in the following fields: electricity, water conservancy, communications, environment, architecture, geology, police, fire, blasting, Marine, railway, counter-terrorism/military, agriculture, forestry, real estate, leisure/field sports, etc.
