NON-INVASIVE MILK DETERIORATION SYSTEM AND METHOD BASED ON LASER SPECKLE CONTRAST IMAGING

摘要

The present invention relates to a milk deterioration detection system (1) and method (100) which detects deterioration or spoiling of milk non-invasively (without contact) via laser speckle contrast imaging. A milk sample (S) is held in a transparent container and deterioration of milk causes the roughness of a transparent surface of said container to change, said changes being monitored by laser speckle contrast imaging.
