Description

Technical Field

[0001] The utility model belongs to the technical field of surveying equipment, and particularly relates to a laser rangefinder. Background Art

[0002] A laser rangefinder is a device that uses laser technology to measure distance. Its working principle is to emit a laser beam, then receive the signal reflected by the laser, and calculate the distance between the target object and the measuring point based on the speed of light and the time difference. The laser rangefinder has the advantages of high measurement accuracy, fast speed, and simple operation. Its measurement accuracy can reach the millimeter level or even higher. Moreover, due to the extremely fast propagation speed of the laser, the measurement speed is very fast, and a measurement calculation can generally be completed within a few seconds. In addition, the operation of the laser rangefinder is also very simple. You only need to aim the emitted laser at the target object and press the measurement button to get the measurement result.

[0003] The main components of the laser rangefinder in the prior art include a laser transmitter, a laser receiver, a data processing module and a display module. The laser transmitter is used to emit a laser beam, the laser receiver is used to receive the reflected laser, the data processing module is used to calculate the measured distance according to the speed of light and the time difference, and the display module is used to display the measurement result. However, when measuring the distance, since the laser emitted by most laser transmitters is invisible light, it will be impossible to distinguish whether the emitted laser is irradiated on the target object. In addition, when measuring long distances, even if the emitted laser is visible light such as red or blue, it is not easy for the human eye to distinguish whether the laser is irradiated on the target object because the target object is far away, resulting in inconvenience in distance measurement.
