Laser Rangefinder Application Note
The laser rangefinder module has the capability to measure a target distance and send the distance information to a host computer. Its compact and lightweight design along with its ease of operation make it a valuable device for efficient measuring. The bonus of its laser source wavelength being in the eye-safe category, making it a worry-free process. Furthermore, this device is customizable to meet your every need.
Operation Principle
The laser rangefinder, as seen in Figures 1 and 2, employs a time of flight principle in which a laser pulse is sent toward the target and the distance is determined based on the total time taken for the pulse to leave the device and get reflected off the target.
The key specifications of the laser rangefinder are listed below in Table 1. We offer a smaller and more compact unit compared to similar products in the market.

Table 1
The laser rangefinder has an operating temperature of negative 40 Degrees Celsius to positive 55 Degrees Celsius and a storage temperature of negative 50 Degrees Celsius to positive 70 Degrees Celsius. The primary functions include single-ranging and continuous-ranging modes with a built-in self-check function.
The main components of a laser rangefinder consist of a laser, a transmitting and receiving optical system, a laser driver, a receiving circuit, a low-voltage power supply, and an information processor. All components work in tandem as seen in Figure 3.
Applications
The laser rangefinder is suitable for use in conditions where visibility is not less than 23km and humidity is less than 50% in the absence of obstacles. It is designed to provide excellent reliability in measurement with a Mean Time Between Failures (MTBF), the number of transmitted laser pulses ≥ 1 million.
The system could be used in but not limited to the following application scenarios:
- Construction Processes
- Real Estate Development
- Industrial Processes
- Laser Measuring Tools
- Security Purposes
- Sports

FAQ
A laser rangefinder is a device that uses a laser beam to measure the distance to a target. Laser rangefinders are often preferred over other types of rangefinders because they provide more accurate measurements and can be used in a wide range of conditions, including low light and adverse weather conditions. They are also relatively small and portable, making them easy to carry and use in the field. Laser rangefinders are commonly used in security, industrial, and civilian applications where accurate distance measurements are critical.
A laser rangefinder typically consists of a laser emitter, a receiver, and a microprocessor. The laser emitter sends out a pulse of laser light, which hits the target and bounces back towards the receiver, which detects the returning light. The time it takes or phase shift for the pulse to travel to the target and back is measured by the microprocessor, which then calculates the distance to the target using the speed of light in the time-of-flight method or using the speed of light, phase change, and modulation frequency in the phase shift method.
