Abstract

The optical axis fine tuning method comprises a light path base main body, a PCB (Printed Circuit Board), a transmitting light path and a receiving light path, and comprises the following steps of: installing a light path element on the transmitting light path or the receiving light path at the center of a pendulum body; a swing bearing hole matched with the swing body is formed in a shell of the optical path base body, and the installation angle of the optical path element is slightly changed by adjusting the swing body to slightly swing in the swing bearing hole, so that the angle of the optical axis is slightly adjusted, and the emitting optical path and the receiving optical path are kept coaxial.

Description

technical field [0001] The invention relates to the technical field of laser measurement, in particular to a method for fine-tuning the optical axis of a laser range finder and the laser range finder. Background technique [0002] Laser ranging instrument is an instrument that uses laser to accurately measure the distance of the target (also known as laser ranging). Laser rangefinders have the advantages of simple operation, high measurement accuracy, long range, and strong anti-interference ability, and are widely used in military and civil affairs. A laser rangefinder usually includes a laser emitting system and a laser receiving system, and the two independent optical systems have their own optical axes. When the laser distance measuring instrument is working, it first uses the laser emitting system to emit a beam of laser light to the measured target, and the scattered laser echo is received by the laser receiving system, so as to determine the distance between the meas...
