AI Technical Summary

Technical Problem

Existing material detection equipment occupies a large area, the arrangement of multiple sensors causes interference, and it is difficult to efficiently detect material properties.

Method used

By combining a spectral system and a laser triangulation system, substances are cross-analyzed within the same detection area using beams and laser lines, reducing equipment space requirements and allowing for the separate or parallel detection of substance properties.

Benefits of technology

This invention enables a compact material detection device, improving detection efficiency and accuracy, reducing sensor interference, and enhancing the ability to analyze material properties.

Abstract

The present invention relates to an apparatus (100) for detecting a substance (102), comprising: a light source device (114) adapted to emit a first set of light beams and a second set of light beams (116, 118) toward a first detection region (104), through which the substance (102) is supplied. A spectroscopic system (120) is adapted to receive and analyze light (122) reflected and / or scattered by the substance (102) in the first detection region. A laser triangulation system (124) includes a laser device (126) adapted to emit a laser line (130) toward a second detection region (106). A camera-based sensor device (128) is configured to receive and analyze light (132) reflected and / or scattered by the substance (102) in the second detection region (106). The light (122) received by the spectroscopic system (120) intersects completely or partially with the light (132) and / or the laser line (130) received by the camera-based sensor device (128).
