METHOD AND DEVICE TO GENERATE A DOT BY DEPOSITING A SPOT ON A MEDIUM USING A VCSEL LIGHT SOURCE

摘要

Method and device to generate a dot (67) on a medium (23) by depositing a spot (22) on a medium (23) using a VCSEL light source (10), whereby a light beam (11) is generated using a VCSEL light source (10), the energy distribution of the generated light beam (11) is reshaped using a wave front engineering element (20) into a light beam (21) with a reshaped energy distribution to deposit a spot (22) on the medium (23).
