| Abstract: | This paper presents a relation between scanning depth of field,the wavelength of scanning light beam and the width of bar code. It also presents three methods of improving the performance for reading bar code in distance. All these methods provide theory basis for extending application fields of bar codein the industry procedure control and the management of enterprise. |
