Detector and detection method for platinum particles on meter-scale laser glass

The invention provides a detector and a detection method for platinum particles on meter-scale to-be-detected laser glass. The detector comprises a detection light source, a light beam varying and shifting mechanism, a to-be-detected laser glass workbench and a control system, wherein the detection light source is composed of a plurality of Nd: YAG lasers, the light beam varying and shifting mechanism comprises multiple light beam varying and shifting modules, the to-be-detected laser glass is placed on the to-be-detected laser glass workbench, the control system controls laser output by the plurality of Nd: YAG lasers to vertically irradiate on a large surface of the to-be-detected laser glass through the light beam varying and shifting modules respectively corresponding to the Nd: YAG lasers, and the control system drives a horizontally movable guide rail on the to-be-detected laser glass workbench to move through a motor so as to drive the to-be-detected laser glass to move, which enables rapid scanning of platinum particles on the to-be-detected laser glass workbench to be realized and allows detection personnel to observe and determine through eyes. The detection method provided by the invention is fast and visualized.
