DISPOSITIF DE MESURE DE DISTANCE À LASER À HAUTE VITESSE

摘要

A high-speed laser distance measuring device comprises an emitting part and a receiving part; the emitting part comprises a polarizer (2) arranged between a light emitting tube (1) and a reflective mirror (3); the receiving part further comprises a polarizing beamsplitter (7) arranged between the optical filter (6) and the receiving tube set; the light emitting tube (1) emits an outgoing light beam to the polarizer (2), and the outgoing light beam forms an outgoing polarized light beam and is transmitted into the reflective mirror (3); after being reflected by the reflective mirror (3) and passing through the transmitting objective lens (4), the outgoing polarized light beam is transmitted onto a target object; after being reflected by the target object, the outgoing polarized light beam forms a reflected polarized light beam, which passes through the receiving objective lens set (5) and is transmitted to the optical filter (6); after being filtered, the reflected polarized light beam is transmitted into the polarizing beamsplitter (7), and is split into a first reflected polarized light beam and a second reflected polarized light beam, which are transmitted into the first receiving tube (8),and the second receiving tube (9) respectively. The high-speed laser distance measuring device is able to identify the light formed by the reflection of an oriented reflective target and a target object, and adopts different receiving means for receiving them; simultaneously, it is able to effectively filter the interference caused by particulate matters in the test environment to the test.
