Presbyopia occurs when the physiologically normal age-related reduction in the eyes
focusing range reaches a point, when optimally corrected for distance vision, that the clarity …

This paper proposes a novel dynamic focusing module driven by galvanometers to position
the laser focus with high speed and high precision. Thanks to the extremely high …

Manipulating the phase and amplitude of light led to many important breakthroughs in
