Movable scanning array in electro-optical readers
摘要:
Scanning in an electro-optical reader for reading indicia is obtained by moving one array of microlenses relative to another microlens array. An outgoing laser beam directed to indicia for reflection therefrom and/or return light reflected from the indicia is steered through a scan angle by the moving array.
