Abstract: The invention regards a method for improving the depth of field in the detection of a linear optical code, comprising simultaneously forming two or more overlapped equally focused but differently diaphragmed in phase images of an optica code onto a linear sensor. Diaphragms and optical receiving devices suitable to implement the method are described.
