Abstract

The invention provides an optical coaxial calibration device and an application method thereof. The device includes a main mirror, a beam splitter, a receiving pentagonal prism, a receiving steering prism, an aiming pentagonal prism, an aiming steering prism, a white light source and a CCD camera; an emitting optical axis is emitted to the main mirror and reflected by the main mirror to focus to the CCD camera; a receiving optical axis passes through the receiving pentagonal prism and the receiving steering prism and is reflected by the main mirror to the CCD camera; an aiming optical axis passes through the aiming pentagonal prism and the aiming steering prism and is reflected by the main mirror to the CCD camera; the emitting optical axis, the receiving optical axis and the aiming optical axis are adjusted to be coaxial with the white light source as the reference; the beam splitter divides a to-be-measured light source into two parts and makes one part of the to-be-measured light source reach the position of the white light source and the other part of the to-be-measured light source reach the position of the CCD camera. According to the optical coaxial calibration device and the application method thereof, the main mirror is small in diameter and weight and convenient to move, and the whole system structure is simple and convenient to operate.

Description

technical field [0001] The invention relates to a calibration device, in particular to an optical coaxial calibration device and a method for using the same. Background technique [0002] In the work of laser range finder, laser radar and other related equipment, the target is irradiated with laser light, and the reflected light signal of the target to the laser is received at the same time. One of the important technical indicators is the need to ensure the consistency of the transmitting and receiving optical axes. The existing optical coaxial calibration device usually includes a large-diameter concave reflector (or large-diameter focusing mirror, usually with a diameter of Above 100mm), bulky, heavy, and inconvenient to move. Contents of the invention [0003] In order to overcome the problems in the related art at least to a certain extent, the present application provides an optical coaxial calibration device and a method for using the same. [0004] The object of ...
