Description

Technical Field

[0001] This utility model relates to the field of rock detection, specifically a laser lithology identification device. Background Technology

[0002] Lithological identification refers to the process of identifying and determining the type and characteristics of rocks through a series of methods and techniques, and comprehensively describing and classifying the mineral composition, structure, texture, color, weathering characteristics, etc. of rocks. The principle of laser lithology identification devices is laser-induced breakdown spectroscopy. A high-energy pulsed laser beam is used to strike the surface of rock fragments. By analyzing the light emitted by the plasma generated when the rock fragments are excited, the chemical composition of the rock can be inferred, thereby determining its lithology. However, because the shapes of the collected rock fragments vary, the angle at which the laser strikes the surface of the rock fragments is different, requiring adjustment of the laser emitter angle. The laser emitter angle of common laser lithology identification devices is mostly fixed, which is inconvenient for angle adjustment and hinders the detection and identification of rock fragment lithology.
