Abstract: A reflective film includes a first optical stack that provides a first reflective characteristic and a second optical stack that provides a second reflective characteristic. The optical stacks also have first and second absorptive characteristics that are suitable to absorptively heat the respective stacks upon exposure to light including a write wavelength while maintaining the structural integrity of the stacks. The absorptive heating can change the first and second reflective characteristics to third and fourth reflective characteristics, respectively. A blocking layer that at least partially blocks light of the write wavelength may also be provided between the optical stacks to permit absorptive heating of any selected one of the optical stacks. The reflective characteristics of the optical stacks can thus be independently modified in any desired patterns by appropriate delivery of light beams that include the write wavelength.

Abstract translation: 反射膜包括提供第一反射特性的第一光学堆叠和提供第二反射特性的第二光学堆叠。 光学堆叠还具有第一和第二吸收特性，其适于在暴露于包括写入波长的光的同时吸收加热各个堆叠，同时保持堆叠的结构完整性。 吸收加热可以将第一和第二反射特性分别改变为第三和第四反射特性。 还可以在光学堆叠之间提供至少部分地阻挡写入波长的光的阻挡层，以允许任何所选择的光学叠层的吸收加热。 因此，可以通过包括写入波长的光束的适当传递，以任何期望的图案独立地修改光学堆叠的反射特性。
