Laser methods for automatic scrap metal sorting
Automatic and accurate scrap metal sorting in recycling plants could give large savings in economy and environment. One key ingredient is fast identification of the composition of each individual metal piece.
Laser Induced Breakdown Spectroscopy (LIBS), is one method of identifying the material constituents of a sample. In LIBS, a high power laser pulse creates a plasma on the surface of the metal piece. The spectrum of the plasma can be used to identify the atomic composition of the sample.
In this project, Acreo develops a LIBS system for analyzing scrap metal. A particular challenge is a large working distance from the laser and sampling head to the metal piece. Field trials of the system are planned for 2011.
