چکیده انگلیسی


• The main causes of field distortion in laser marking were analyzed deeply.
• A new correction method was proposed considering variety of factors.
• The group experiments show that the correction method is workable.

Because of inherent and random errors, the pillow-shaped and barrel-shaped distortions are occurred in the embedded laser marking system. These seriously affect marking quality. However, the existed correcting approaches are almost all used on PC based laser marking controller. They require very high processing speeds of the processor which cannot be satisfied in the embedded controller. In order to find a suitable method, the causes of distortions were analyzed deeply. After that, a linear compensation method is put forward herein. It needs to determine two coefficients by standard process and tries to improve the marking quality by compensating the marking data before converted to voltage by digital-to-analogue converter. It is not complex as the PC based one, but can correct the distortions to some extent. Experiments show that this method can efficiently decrease the distortions and improve the marking quality.
