Features and Applications of Laser Infrared Range Finder
Features: cheap, easy to make, safe, low accuracy, high refractive index when crossed with other substances. The infrared photoelectric rangefinder has the characteristics of low precision, weak flexibility, fast operation, and great influence of terrain. The photoelectric rangefinder, the electronic theodolite and the computer form the electronic speedometer. It can measure the horizontal distance, horizontal angle and vertical angle at one station at the same time, so as to obtain the height difference and coordinate increment of the point to be set, and record electronic data, so that all the measurement work of the measuring station can be completed automatically, which greatly simplifies the measurement Work.
2. Introduction: As an optical distance meter, it has been widely used in various fields. Range finders can be divided into ultrasonic range finders, infrared range finders and laser range finders. The latter two rangefinders are no longer produced due to limitations in accuracy and range. At present, the infrared range finder refers to the laser infrared laser range finder, that is, the laser range finder. Infrared rangefinder - an instrument that uses modulated white light for optical distance measurement, and the range is usually 1-5 kilometers.
3. Working principle: Utilizing the non-diffusion principle of infrared transmission, because infrared rays pass through other substances, the refractive index is very large, so the long-distance range finder will consider infrared rays. The propagation of infrared rays takes time. When the infrared rays emitted by the rangefinder hit the mid-reflector, they are reflected back and received by the rangefinder. Then the distance can be calculated according to the time from sending to receiving the infrared ray and the transmission speed of the infrared ray. The magnet of the laser infrared measuring instrument is called the magnet of the laser infrared photoelectric rangefinder in the industry, which is a specific high magnetic permanent magnet.
4. Application method: first place the infrared rangefinder on the front, press and hold the red triangle key on the machine with your right hand, this is to locate the target to be measured, and the display screen on the machine will also display the value of the distance. It is known that since the accuracy of the infrared rangefinder has a certain relationship, it is best to measure during the day.
Because many infrared range finders and lasers are relatively effective configurations, we must refer to the instructions in the instrument manual when using them, and do not directly aim at the emission port with the eyes, which will cause a small damage to the eyes. Injury, in the field measurement work, the transmitter of the instrument cannot coincide with the sun, which will cause a small damage to the photosensitive element of the instrument. It should be noted here that the infrared range finders on the market usually do not have waterproof function, so pay attention to waterproof work during the process of using the machine.
Infrared rangefinders are widely used in topographic surveys, battlefield surveys, tanks, aircraft, ships and artillery to measure the distance of targets, measure cloud heights, measure aircraft, missiles and satellites, etc. It is the key technical equipment to improve the accuracy of tanks, aircraft, ships and artillery. With the continuous decline in the price of laser infrared range finders, infrared laser range finders have gradually begun to be used in the industry, which can be widely used in industrial control, mines, ports and other fields.
