防爆激光测距仪讲解

一些客户问：煤矿需要购买一批防爆激光测距仪，是否有手持式，携带更方便的激光测距仪。那么，手持式方便激光测距仪有什么用呢？我相信很多人都不知道。小编会给你看的。

顾名思义，激光测距仪是一种测量距离的仪器。煤矿地下采用手持式防爆激光测距仪，准确快速测量巷道、工作面、采矿面等距离和高度，计算面积和体积。也可用于安全监督执法领域，准确快速地测量执法现场，计算面积和体积。可广泛应用于工业、商业装饰、工程建设等领域。可用于地砖铺设；估算墙面涂料面积；现场施工距离/面积/体积测量等。与望远镜激光测距仪相比，精度高(望远镜激光测距仪精度为1m）、显示屏的大优点。从测距的基本原理来看，可分为激光测距仪、超声波测距仪和红外测距仪。目前，激光测距仪广泛应用于测距仪。激光测距仪用激光准确测量目标距离。激光测距仪在工作时向目标射出一束非常细的激光，从观测距仪到接收目标的时间。

1. 激光测距的原理是什么？测距原理基本上可以归因于测量光往返目标所需的时间，然后通过光速c =m/s 大气折射系数n 计算距离D。由于直接测量时间困难，通常称为测量连续波的相位。.被测物体的平面必须垂直于光线吗？通常，精密测距需要全反射棱镜。房屋测量的测距仪直接用光滑的墙体反射，主要是因为距离相对较近，光反射的信号强度足够大。你知道，垂直，否则返回信号太弱，无法获得准确的距离。.如果被测物体的平面是漫反射，可以吗？一般来说，薄塑料板将用作实际工程中的反射面，以解决漫反射严重的问题。

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.
