Patent ID: 7525707

Claim:
A system for patterning a surface, comprising: an energetic beam source, operable to emit an energetic collimated beam, wherein the beam is operable to locally heat an illuminated region of the surface; two optical devices, each comprising: a first reflective optical element, operable to rotate around a first respective axis; a second reflective optical element, operable to rotate around a second respective axis, wherein the first respective axis and the second respective axis are parallel; and at least one actuator coupled to the first and second reflective optical elements, and operable to respectively rotate the first and second reflective optical elements around the first and second respective axes in a coordinated manner such that the first and second reflective optical elements are parallel, wherein the optical device is operable to perform a parallel displacement of the beam in a respective direction, and wherein the respective direction is orthogonal to the beam; wherein the two optical devices comprises a first optical device and a second optical device, wherein the first optical device is operable to: receive the beam from the beam source; displace the beam in a first direction; and transmit the displaced beam to the second optical device; wherein the second optical device is operable to: receive the displaced beam from the first optical device; displace the beam in a second direction; and transmit the displaced beam to the surface; wherein the second direction is orthogonal to the first direction; and wherein the two optical devices are operable to direct the beam to illuminate and locally heat a sequence of specified regions of the surface to pattern the surface.
