Description

Laser measurement distance calibration equipment

Technical Field

The invention relates to the field of laser tools, in particular to laser measurement distance calibration equipment.

Background

A laser rangefinder is an instrument that uses a parameter of modulated laser light to achieve a distance measurement to a target. The distance measuring method is divided into a phase method distance measuring instrument and a pulse method distance measuring instrument, the pulse type laser distance measuring instrument emits a pulse laser beam or a sequence of short pulse laser beams to a target when in work, a photoelectric element receives the laser beam reflected by the target, a timer measures the time from the emitting to the receiving of the laser beam, and the distance from an observer to the target is calculated. The phase-method laser range finder detects a distance by detecting a phase difference occurring when emitted light and reflected light propagate in a space. The laser range finder has light weight, small volume, simple operation, high speed and accuracy, and the error is only one fifth to one hundred times of that of other optical range finders. The principle of infrared ranging or laser ranging is utilized: the distance measurement principle can be basically summarized as measuring the time required for the light to travel to and from the target, and then calculating the distance D by the speed of light c =299792458m/s and the atmospheric refractive index n. Because of the difficulty in directly measuring time, it is common to determine the phase of a continuous wave, known as a phase-finding rangefinder. The object plane must be perpendicular to the light: the general precision distance measurement needs the cooperation of total reflection prism, and the distancer of house measurement usefulness directly measures with smooth wall reflection, mainly because the distance is nearer, and the signal intensity that light reflection was come back is big enough. It can be known that the signal must be vertical, otherwise the return signal is too weak to obtain an accurate distance. The object plane can be measured as diffuse reflection: it is also generally possible that a thin plastic plate is used as a reflecting surface in practical engineering to solve the problem of severe diffuse reflection. The entertainment-grade product of the pulse method laser range finder can achieve the display precision of 1 meter, the measurement precision of +/-1 meter, the display precision of 0.1 meter and the measurement precision of +/-0.15 meter. The precision of the phase type laser range finder can reach 1 mm error, and the phase type laser range finder is suitable for various high-precision measurement purposes.

Although the conventional laser range finder with the patent number of CN201320455651.0 can make the operation of the laser range finder simpler and easier, and can reduce the cost at the same time, the laser range finder does not have a corresponding supporting and adjusting device, so that the laser range finder can be used on the ground when the laser range finder needs to be placed on the ground, and when the ground has a certain slope, the deviation between the measured data and the actual data is generated, thereby finally reducing the reliability of the laser range finder.
