Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 As shown, it is a typical laser ranging installation structure in the prior art, including a conventional laser device 7, a laser emitting unit 8 and a laser receiving unit 9 are integrated inside the laser device 7, and the target 4 to be ranged is located in the laser device In the direction of the laser irradiation light path of 7, starting at a certain moment, the laser emitting unit 8 emits a laser signal from the target 4 to be range-measured, and the laser receiving unit 9 receives the echo laser signal from the target 4 to be range-measured, and calculates the laser signal from The time required for the laser emitting unit 8 to arrive at the target 4 to be range-measured and return to the laser receiving unit 9 is used to calculate the distance to be measured d, the time required for the pulse signal to go back...

Abstract

The invention discloses a laser range finder structure applied to a low range, which comprises a laser device, a right angle prism, a single-sided mirror, and either a laser high reflection mirror or a bimirror, wherein the laser device is internally integrated with a laser transmitting unit, a laser receiving unit and a data processing unit. According to the structure of the invention, through reflection or refraction of the right angle prism, the single-sided mirror, the laser high reflection mirror or the bimirror, a laser signal path is changed, and the problems that the laser device is inconvenient to mount due to limited space in the Y direction and the laser range finder is low in precision and large in errors due to small to-be-found range can be effectively solved; and the structure is simple, the cost is low, the mounting is convenient, and the low-range laser range finder precision is improved.

Description

technical field [0001] The invention relates to the technical field of laser measurement, which is used for short-distance measurement with limited installation environment distance and high precision requirements, and relates to a laser ranging structure suitable for low range. Background technique [0002] Laser has the advantages of strong directionality, high brightness, good monochromaticity, and good coherence. It also has high measurement accuracy and wide range, and realizes non-contact measurement. It is widely used in the field of distance measurement. The laser distance measuring device utilizes the characteristic that the propagation speed of the laser is basically constant in the air, and generally realizes the distance measurement by the round-trip time of the laser signal on the distance of the target to be measured. In recent years, with the development of laser technology, electronic technology and computer technology, laser ranging technology has developed ...
