What is the measuring principle of laser rangefinder?
A laser rangefinder is an instrument that USES a laser to accurately measure the distance between policies.The laser rangefinder shoots a very fine laser rangefinder light to the target when it is operating. The laser beam reflected by the acceptance target of the photoelectric element is measured by the timer. The timer measures the time of the laser beam from emission to acceptance and calculates the interval between the observer and the target. If the laser is continuously launched, the range can be up to about 40 km, lined with fluorine butterfly valve and can be operated day and night.If the laser is pulse emission, the general accuracy is certainly low, but used for distant interval quantity, can reach a very good relative accuracy.The world's first laser was first developed in 1960 by hughes aircraft company scientist maiman.
The U.S. military soon began a study of military laser equipment based on this.In 1961, the first military laser rangefinder passed the U.S. military's certified test, and soon after that the laser rangefinder entered a useful combination. Laser rangefinder heavy weight, small volume, simple operation, fast and accurate, its error is only one 5 of other optical rangefinder to one percent, and therefore is widely used in terrain measurement, field measurement, tanks, planes, ships and artillery range of policies, measurement of clouds, the height of the aircraft, missiles and satellites, etc. It is an important technical equipment to improve the precision of high tanks, aircraft, ships and artillery.Because the price of laser rangefinders continues to fall, the industry has gradually begun to use laser rangefinders.A number of new micro rangefinders with the advantages of fast ranging, small size and reliable function have appeared at home and abroad, which can be widely used in industrial measurement and control, mining, port and other fields.The primary classification of one-dimensional laser rangefinder used for interval measurement and location;Scanning Laser Rangefinder (2d) is used in Scanning Laser Rangefinder for general measurement, positioning, regional monitoring and other fields.3D Laser Rangefinder (3D Laser Rangefinder) is used in the fields of 3D general measurement and 3D spatial positioning.
1. Must the plane of the subject be straight with the light?
General precision ranging needs total reflection prism, and the house measurement with the rangefinder, directly with the lubrication of the wall reflection measurement, the first is because the interval is relatively close, light reflection back signal strength is large enough.This can be known, must be straight, otherwise the return signal is too weak to get the exact spacing.
2. What is the principle of infrared ranging or laser ranging?
The ranging principle can be basically summed up as measuring the time required for the round-trip policy of light, and then calculating the interval D by the light velocity c =299792458m/s and the atmospheric refraction coefficient n.Because it is difficult to measure time directly, the phase of continuous wave is usually measured.Of course, there is also a pulse rangefinder, which is typical of WILD di-3000. Please note that the phase measurement is not to measure the phase of the infrared or laser, but to measure the modulation of the signal phase above the infrared or laser.The construction industry has a hand-held laser rangefinder for measuring houses that works on the same principle.
3. If the plane of the measured object is diffuse reflection, is it possible?
It is generally possible to use thin plastic sheets as reflective surfaces in practical projects to deal with serious diffuse reflection problems.
How to maintain laser rangefinder?
Laser rangefinders generally use two methods to measure the interval: 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 coming and going.Half the product of the speed of light and the time to go back and forth is distance measurement.
Maintenance and protection methods of laser rangefinder:
Hand-held rangefinder protection:
In daily life, interior planner and architect often face a problem, it is in planning and adornment process, because a few cannot be close to the address of measure all sorts of measure difficulty to exist perhaps safety hidden trouble and have a headache.Now, laser rangefinders can do a good job for you, easily measuring all sorts of distances that can't be close to an address or the length of an object.
Local handheld laser rangefinders that do not have direct access to measurement guidelines, such as stairwells and elevators, can help you with measurement, replacing the traditional box measurement and saving manpower.Laser rangefinder is a new high function handheld rangefinder launched in recent years, the use of patent planning, measuring range is 0.05~200m, measurement accuracy is ±1-±1.5mm, measurement fast, easy to use, planning fine, can be carried around.With this laser rangefinder, you can measure the volume of the house or stairwell without the need for lifting platform or extension ladder, and the accurate reading can be taken in a few seconds.
In addition, the rangefinder in addition to pocket portable planning, but also with the addition of length subtraction function, not due to the measurement of the ceiling and crouched on the ground.With a large LCD backlit display screen, this laser rangefinder enables you to easily read measurement data together with your eye alignment.With a laser rangefinder, one person can get to work and do it twice as fast as usual.
