防爆激光測距儀講解

一些客戶問：煤礦需要購買一批防爆激光測距儀，是否有手持式，攜帶更方便的激光測距儀。那么，手持式方便激光測距儀有什么用呢？我相信很多人都不知道。小邊會給你看的。

激光測距儀是一種測量距離的儀器，顧名思義。煤礦地下采用手持式防爆激光測距儀，準確快速測量巷道、工作面、采礦面等距離和高度，計算面積和體積。也可用于安全監督執法領域，準確快速地測量執法現場，計算面積和體積?？蓮V泛應用于工業、商業裝飾、工程建設等領域?？捎糜诘卮u鋪設；估算墻面涂料面積；現場施工距離/面積/體積測量等。與望遠鏡激光測距儀相比，精度高(望遠鏡激光測距儀精度為1m)、顯示屏的大優點。根據測距的基本原理，可分為激光測距儀、超聲波測距儀和紅外測距儀。目前，激光測距儀廣泛應用于測距儀。激光測距儀用激光準確測量目標距離。從觀測距儀到接收目標的時間，激光測距儀在工作時向目標射出一束非常細的激光。

1. 激光測距的原理是什么？測距原理基本上可以歸因于測量光往返目標所需的時間，然后通過光速c =m/s 大氣折射系數n 計算距離D。由于直接測量時間困難，通常稱為測量連續波的相位。.被測物體的平面必須垂直于光線嗎？精確測距通常需要全反射棱鏡。房屋測量的測距儀直接用光滑的墻體反射，主要是因為距離比較近，光反射的信號強度足夠大。你知道，垂直，否則返回信號太弱，無法獲得準確的距離。.如果被測物體的平面是漫反射，可以嗎？一般來說，薄塑料板將用作實際工程中的反射面，以解決漫反射嚴重的問題。

A customer asked: coal mine need to purchase a number of explosion-proof laser rangefinder,whether there is a handheld,portable laser rangefinder. So what's the use of portable laser rangefinder? I believe ny people don't know. I'll give you a stroke.

As the name implies,the laser rangefinder is a distance measuring instrument. The handheld explosion-proof laser rangefinder is used in underground coal mines to accurately and rapidly measure the distance and height of roadway,working face and mining face,and can calculate the area and volume. It can also be used in the field of safety supervision and law enforcement to accurately and quickly measure the law enforcement scene,and calculate the area and volume. It can be widely used in industrial,commercial decoration,engineering construction and other fields. It can be used for floor tile laying,wall coating area esti tion,site construction distance / area / volume measurement,etc. Compared with the telescope laser rangefinder,it has the advantages of high precision (the precision of telescope laser rangefinder is 1 meter) and the display screen is large.

From the basic principle of ranging,it can be divided into three categories: laser rangefinder,ultrasonic rangefinder and infrared rangefinder. Laser ranging ceremony is currently widely used in rangefinder,which uses laser to accurately measure the distance of the target. The distance from the receiving laser beam to the target is measured by the time from the receiving laser beam to the target.

Common problems of handheld laser rangefinder:

1. What is the principle of laser ranging?

The principle of ranging can be summed up as measuring the time required for light to and from the target,and then the distance D can be calculated by the light speed c = m / s and atmospheric refraction coefficient n. Because it is difficult to measure time directly,it is usually to measure the phase of continuous wave.

2. Must the plane of the measured object be perpendicular to the light?

In general,precise ranging requires the cooperation of total reflection pri ,while the rangefinder used for house measurement directly uses ooth wall reflection measurement, inly because the distance is relatively close,and the signal intensity reflected by light is large enough. With this we can know,to vertical,otherwise the return signal is too weak will not be able to get the accurate distance.

3. If the plane of the measured object is diffuse reflection,is it OK?

Generally,it is also possible to use thin plastic plate as reflection su ce to solve the serious problem of diffuse reflection.
