Device for identification of e.g. article, has laser device, detection unit and processing unit integrated in handheld unit that has inlet and outlet arranged adjacent to each other in distance of ten cm or smaller

摘要

#CMT# #/CMT# The device has a laser device (102) for delivering a laser pulse (104) to convert chemical elements in a portion of a mark (100) into plasma. A detection unit (108) i.e. detector, detects electromagnetic radiation (106) emitted by the plasma. A processing unit (110) evaluates the radiation or its characteristic property, and provides a signal based on information in the mark to identify an object (114). The laser device, detection unit and processing unit are integrated in a handheld unit (116) that has an inlet and an outlet arranged adjacent to each other in a distance of 10 cm or smaller. #CMT# : #/CMT# The detection unit is formed as spectrometer e.g. wide band spectrometer, prism spectrometer or grid spectrometer. The mark is numerical code or bar code. An independent claim is also included for a method for identification of an object. #CMT#USE : #/CMT# Device for identification of an object e.g. article, living organism such as person and pet animal e.g. horse and cow, and motor car. #CMT#ADVANTAGE : #/CMT# The device enabling efficient, inexpensive and mobile reading of the marks attached in the object. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of a device for reading of a mark.'(Drawing includes non-English language text)' 100 : Mark 102 : Laser device 104 : Laser pulse 106 : Electromagnetic radiation 108 : Detection unit 110 : Processing unit 114 : Object 116 : Handheld unit #CMT#METALLURGY : #/CMT# The chemical elements are metals e.g. aluminum, iron, gold, copper, magnesium and zinc.
