Title:
COORDINATED SCANNING AND POWER CONTROL OF LASER FOR FORMING STRUCTURES IN OPHTHALMIC LENSES
Document Type and Number:
WIPO Patent Application WO/2022/203916
Kind Code:
A3
Abstract:
Methods and systems for coordinating pulse powers and focal positions of laser beam pulses used to form a subsurface optical structure. Focal positions for a sequence of laser beam pulses may be stored in a scanning controller configured for controlling operation of a scanning assembly to scan the sequence of laser beam pulses to focal positions in the ophthalmic lens. A memory associated with a power controller may store pulse power data values corresponding to pulse powers for the sequence of laser beam pulses. The power controller can control a pulse power control assembly based on the pulse power data values. Operation of the scanning controller may be synchronized with operation of the power controller during scanning of the sequence of laser beam pulses to the focal positions in the ophthalmic lens via communication of one or more trigger signals between the scanning controller and the power controller.
