Embodiment Construction

[0037] Such as figure 1 As shown, the high-precision laser displacement sensor that can prompt the focusing direction includes a housing 1 with a cavity inside.

[0038] The housing 1 is connected with a dual-frequency laser 2 , a beam splitter 3 , a field mirror 4 and a photocell 5 , and the beam splitter 3 is used to receive the laser light emitted by the dual-frequency laser 2 . The housing 1 also has a triangular ranging sensor mechanism for receiving one of the light beams at the light output end of the beam splitter-3, and an off-axis beam displacement sensor mechanism for receiving the other beam at the light output end of the beam splitter-3.

[0039] The triangular ranging sensing mechanism can detect whether the light beam reflected by the measured object 8 can be projected, and the above-mentioned off-axis beam displacement sensing mechanism can make the light beam reflected by the measured object 8 enter the photocell 5 through the field lens 4 Formation of spots....

Abstract

The invention provides a high-precision laser displacement sensor capable of prompting the focus direction, which belongs to the technical field of machinery. It solves the problems of cumbersome adjustment and low adjustment accuracy of existing sensors. The high-precision laser displacement sensor that can prompt the focus direction includes a housing, and the housing is connected with a dual-frequency laser, beam splitter 1, field mirror and photocell, and the beam splitter 1 is used to receive the output from the dual-frequency laser. Laser, the housing also has a triangular ranging sensor mechanism for receiving one of the light beams at the light output end of the beam splitter, and an off-axis beam displacement sensor mechanism for receiving the other beam at the light output end of the beam splitter. The triangular ranging sensing mechanism can detect whether the light beam reflected by the measured object can be projected, and the above-mentioned off-axis beam displacement sensing mechanism can make the light beam reflected by the measured object enter the photocell to form a light spot through the field mirror. The sensor is easy to adjust and has high precision.

Description

technical field [0001] The invention relates to a sensor, in particular to a high-precision laser displacement sensor that can prompt the focusing direction. Background technique [0002] A sensor is a detection device that can feel the measured information, and can convert the detected information into electrical signals or other required forms of information output according to certain rules, so as to meet the needs of information transmission, processing, storage, display, recording and control requirements. It is the first link to realize automatic detection and automatic control. Sensors are widely used in various fields of social development and human life, such as industrial automation, agricultural modernization, aerospace technology, military engineering, robotics, resource development, ocean detection, environmental monitoring, security, medical diagnosis, transportation, household appliances Wait. [0003] Geometric error measurement is an important prerequisit...
