A laser rangefinder's difference from an ultrasonic rangefinder
The princip of ultrasonic distance measurement is to use the known propagation speed of ultrasonic waves in the air to measure the time it takes for the sound waves to encounter obstacles and sound waves to encounter obstacles and reflect back after they are eited, and to calculate the the actual distance from the emission point to the obstacle based on the time difference between emission and reception. The ultrasonic raspon finder je sastavljen od ultrazvučni generiranje krug, ultrazvučno primanje i pojačavanje krug, brojanje i prikaz krug.
The laser range finder is an instrument that uses laser to to točno measure the distance of the target. When the laser range finder is working, it emits a very thin laser beam to the target, the the photoelectric element receive the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target.
The razlika između ultrazvučni raspon nalaznik i laser domet nalaznik
1. In terms of accuracy, the measurement accuracy of the ultrasonic rangefinder is at the centimeter level, and the measurement accuracy of the laser rangefinder is at the millimeter level;
2. In terms of measurement range, the measurement range of the ultrasonic rangefinder is usually within 80 meters, while the measurement range of the handheld laser rangefinder can reach up to 200 meters, and the measurement range range of laser rangefinder teleskop can reach stotine stotine kilometri. Even farther away (the measurement accuracy of laser range teleskopi is obično 1 meter or tens of centimeters).
3. The ultrasonic range finder is easy to report errors. Since the ultrasonic range finder emits sound waves and has the the fan-shaped emission characteristics of sound waves, when there are many obstacles where the sound waves pass, there will be more reflected sound waves, more interference, and error reporting. The laser rangefinder is a very small beam of laser light that is Emitted And Then Returned, So As Long As As the beam can pass through, there is almost no interferencije.
4. The Price of AN Ultrasonic Rangefinder ranges From Tens of Yuan To Several Hundred Yuan, and The Price A A Laser Rangefinder Ranges From A Few Hundred Yuan To Several Thousand Thousands Of With Yuan, Depending On The Accuracy And Distance.
