Abstract:
1. A method of optically reading varying optical reflectivity along respective orthogonal axes of an information area, comprising the steps of: (a) positioning a user-supported optical reader, the optical reader containing a photosensor capable of reading along row and column pixel axes, such that orthogonal axes of an information area to be read occupy a range of angular relationships to the pixel axes along which the photosensor reads; (b) focusing the user-supported optical reader on the information area; (c) imaging, for said range of angular relationships, the information area onto the photosensor so that the information content of the information area is imaged onto the photosensor without requiring prior angular movement of the user-supported optical reader; and (d) generating a digital representation of the information content imaged from the information area onto the photosensor for any angular relationship between said orthogonal axes of the information area and the pixel axes along which the photosensor images.
