Title:
CROSS LINE LASER
Document Type and Number:
WIPO Patent Application WO/2018/171277
Kind Code:
A1
Abstract:
A cross line laser comprises: a laser source module for emitting a laser beam; a micromirror optical module for receiving and reflecting the laser beam to a target object, the target object reflecting the laser beam back to the micromirror optical module to form a reflected laser beam; an optical detection module for receiving the reflected laser beam and converting the reflected laser beam into an electric signal; a data processing module connected to the optical detection module, the data processing module receiving the electric signal and performing computation to obtain distance data with respect to the target object. In the present invention, a conventional laser module structure is replaced with a galvanometer structure, such that a projected laser beam is programmable, thereby providing more options than fixed combinations of points and lines. Patterns of laser rays projected by an instrument can be set according to actual needs, thereby providing great convenience in construction.
