Abstract

The invention discloses a great-depth OCT (optical coherence tomograph) scanning device for nearly transparent minerals. The great-depth OCT scanning device comprises a weak coherent light source part, a laser light path part, a sample arm light path part, a reference arm light path part, a system calibration unit, a system light signal receiving unit and a signal processing unit, wherein the weak coherent light source part comprises weak coherent light sources and a polarization controller, and required polarization radiation light can be output by adjusting the polarization controller. The device does not damage the nearly transparent minerals, has no special requirement for the environment and performs non-destructive detection on the nearly transparent minerals. The device adopts a unique laser light path system, combines the characteristic of long travel of an electric linear translation unit, performs great-depth longitudinal optical path scanning on the insides of the nearly transparent minerals, can know conditions of the insides of the nearly transparent minerals more accurately and comprehensively and adopts the unique system calibration unit and a great-depth optical path scanning device, the system detection accuracy error can reach the micron scale, the accuracy is high, and the detection range is large.

Description

technical field [0001] The invention relates to the technical field of near-transparent mineral detection, in particular to a large-depth OCT scanning device and method for near-transparent minerals. Background technique [0002] The extraction or processing of near-transparent minerals requires the assistance of different types of detection instruments. Before minerals are processed, they are checked for quality. [0003] Due to the flaws (such as cracks and impurities) in the near-transparent mineral itself, if the flaws are not detected before processing, the final processed product may not be of high quality or even become a defective product due to the flaws. The utilization rate of raw materials is not high, causing great losses. [0004] For high-precision modern processing, high-precision detection device equipment is very critical. [0005] The traditional measurement method uses ultrasonic echo technology, which sends out ultrasonic waves through an ultrasonic g...
