摘要:
In a laser delivery system for an ophthalmic laser surgery system, a laser beam scanner employs a single or two MEMS micromirror arrays. Each micromirror in the array is capable of being independently actuated to rotate to desired angles. In one embodiment, one or two micromirror arrays are controlled to scan a laser beam in two directions. In another embodiment, a micromirror array is controlled to both correct optical aberrations in the laser beam and scan the laser beam in two directions. In yet another embodiment, a micromirror array is controlled to cause the laser beam to be focused to multiple focal spots simultaneously and to scan the multiple focal spot simultaneously. The ophthalmic laser surgery system also includes an ultrashort pulse laser, a laser energy control module, focusing optics and other optics, and a controller for controlling the laser beam scanner and other components of the system.
