Paprastai, the 200m range finder is a handheld device, and the shape of the large range is similar to that of a telescope, also called: a range finder.
Matavimas principas ir funkcija metodas
Su the development of science and technology, it seems that most people don't know about laser range finders, and don't understand laser range finders. Some workers even use measurement tapes to measure distances, and use pens to calculate areas, volumes, and so on. Let me introduce the principle and usage of the laser range finder, which can allow workers to work and study with high efficiency and didelis tikslumas.
The laser rangefinder is an instrument that uses laser to accurately measure the distance of the target. When the laser range finder is working, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculate the distance from the observer to the target.
If the laser is emitted continuously, the measurement range can reach about 40 kilometrų, and the operation can be carried out day and night. If the laser is emitted in pulses, the accuracy is generally low, but for long-distance measurement, good relative accuracy can be reach.
The world's first laser was successful developed in 1960 by Maiman, a scientist from the Hughes Aircraft Company of the United States. The U.S. military soon launched research on advanced laser devices on this basis. In 1961, the first laser range finder passed the demonstration test of the US military, after which the laser range finder soon entered the practical complex.
The laser range finder is light in weight, small in size, easy to operation, fast and accurate, and its error is only one-fifth to s scendreds of other optical range finders, so it is wide used in terrain measurement, battlefield measurement, tank , Aircraft, ships and artillery to the target range, measurement the altitude of clouds, aircraft, missiles and artificial satellites, etc. It is an svarbu techninė įranga to tobulinti the accuracy of high tanks, aircraft, ships and artillery.
Due to the continuous reduction in the price of laser range finders, the industry has gradually begun to use laser range finders. A batch of new miniature rangefinders with the advantages of fast ranging, small size and reliable performance have emerged at home and abroad, which can be wide used in industrial measurement and control, mines, ports and other fields.

1. Kas yra the principas of using infraraudonųjų spindulių ranging or laser ranging?
The principle of ranging can basically be atmos: to measurement the time required for light to go back and forth to the target, and then calculate the distance D through the speed of light c=299792458}m/s and the atmospheric refraction coefficient n. Because it is sunku to matas laikas tiesiogiai, it is paprastai to matas the phase of continuous wave, which is called phase measurement range finder. Of course, there are also pulse rangefinders, typically WILD's DI-3000
It should be noted that phase measurement does not measure the phase of infrared or laser, but the phase of the signal modulated on infrared or laser. The construction industry has a handheld laser distance meter for house surveying that works on the same principle.
2. Must the plane of the measured object be perpendicular to the light?
Paprastai tikslumas atstumas matavimas reikalauja bendradarbiavimas a iš viso atspindys prizmė, o the rangefinder used for house measurement directly measures with smooth wall reflection, daugiausia nes the distance is relate short and the signal strength of the light reflected back is large enough. It can be known from this that it must be vertical, otherwise the return signal is too weak and the maximum distance cannot be gauta.
3. Is it įmanoma jei the plane of the measured object is diffuse reflection?
It is paprastai įmanoma. In faktinis inžinerinis, a plonas plastikas plokštė is naudotas as a atspindintis paviršius to solve the problem of serious diffuse reflection.
4. The accuracy of ultrasonic ranging is reliatively low, and it is rare used now.
