Abstract
A dataform reader module is provided utilizing a piezoelectric reflector with a reflecting angle that is adjustable to provide for an optimal focus of an image projected onto a photosensor array. A distance measurement device can provide a distance measurement utilized in adjusting the piezoelectric reflector, such that an optimal focus can be made without the use of multiple lenses and/or reflectors. Alternatively, various dataform readings can be performed to find the optimal focus without employing a distance measurement device. Additionally, distance measurements and readings can be performed on segments of the dataform and the dataform reconstructed after all of the readings have been performed.
