Rutina priežiūra ir lazeris diapazonas ieškikliai principas
Lazeris nuotolio ieškiklis priežiūra:
② Kai valymas the okuliaras, objektyvas lęšis arba lazeris emisija langas, naudojimas a minkštas sausas šluostė. It yra griežtai draudžiama į su su kietais objektais, so as ne to damage the optical performance.
③ This machine is a high-precision instrument integrating light, machinery and electricity. It should be handled with care during use. It is strictly forbidden to squeeze or drop from a high place to avoid damage to the instrument.
Problemos kad reikia to be paid attention to when using: The laser rangefinder cannot be aimed at the human eye for direct measurement to prevent damage to the human body. At the same time, the general laser rangefinder of the vibration meter is not waterproof, so it needs to pay attention to waterproofing. , so the advantage of the production is that it can be waterproof and anti-fog, and it is įrengta su džiunglėmis medžiais šakomis ir lapais.
The laser does not have the function of anti-drop, so the laser rangefinder is easy to break the light emitter.
principas
1. Objektas plokštuma gali būti išmatuota as difuzija atspindys
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.
2. Principas naudojimas infraraudonųjų spindulių diapazonas arba lazeris diapazonas
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 range finders, 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.
3. The accuracy of the laser rangefinder can reach 1 mm error, which is suitable for įvairiems high-precision measurement tikslais.
Problems that need to be paid attention to when using the laser rangefinder: The laser rangefinder cannot be aimed at the human eye for direct measurement to prevent damage to the human body. At the same time, the general laser rangefinder of the vibration meter is not waterproof, so it needs to pay attention to waterproofing. The American Leoport laser rangefinder is mainly suitable for outdoor hunting enthusiasts in the United States, so the advantage of its production is that it can be waterproof and anti-fog, and it is equipped with jungle tree branches and leaves.
4. The plokštuma of the measured object must be statmena į 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 relatetively 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 distance cannot be gauta.
