Laser ranging sensor is an instrument that uses laser to accurately measure the distance of a target. The laser ranging sensor emits a very thin laser beam towards the target during operation, and the reflected laser beam is received by the photoelectric element. The timer measures the time from emission to reception of the laser beam and calculates the distance from the observer to the target.
If the laser is continuously emitted, the measuring range can reach about 40 kilometers and it can operate day and night. If the laser is pulsed, the absolute accuracy is generally low, but when used for long-distance measurements, it can achieve good relative accuracy.
The world's first laser was successfully developed by scientist Meiman from Hughes Aircraft Company in 1960. The US military quickly conducted research on military laser devices based on this foundation. In 1961, the first military laser rangefinder sensor passed the US military demonstration test, and soon after, the laser rangefinder entered the practical consortium.
Laser ranging sensors are lightweight, small in size, easy to operate, fast and accurate, with errors only one-fifth to one hundredth of other optical rangefinders. Therefore, they are widely used for terrain measurement, battlefield measurement, tank, aircraft, ship and artillery ranging of targets, measuring the height of clouds, aircraft, missiles and artificial satellites. It is an important technical equipment for improving the accuracy of high tanks, aircraft, ships, and artillery.
Due to the continuous decrease in the price of laser ranging sensors, the industry has gradually begun to use laser ranging sensors. A new batch of miniature rangefinders with advantages such as fast ranging, small size, and reliable performance have emerged both domestically and internationally, which can be widely used in industrial measurement and control, mining, ports, and other fields.
The application of laser ranging sensors: industrial liquid level, material level, production line billet conveying positioning, XY positioning for lifting, and assembly positioning for large workpieces; Geometric measurement of oversized objects, light scattering tests, ultrasonic characteristic tests, military firearm calibration, automatic target distance control, safe berthing distance of ships, container positioning and other fields. Due to its online continuous detection, it eliminates the need for manual monitoring like handheld laser rangefinders, allowing for unmanned continuous monitoring. Its position data can also be transmitted to remote monitoring terminals, making it an ideal instrument for industrial automation and intelligent production management.
Laser ranging sensor is a new generation of ranging equipment, powerful, sturdy and durable, designed specifically for the industrial measurement market. This device has many outstanding performances It is currently the most advanced economical online position detection system, with astonishing testing accuracy and extremely high stability. Due to the fact that the distance is accurately calculated by emitting a laser beam to the target object and using the reflected beam, it is possible to achieve a long detection distance without adding a reflective target. Moreover, the size and area of the target object are much smaller than the area required by ultrasound, making it possible to detect the position of small-sized objects at long distances.
