SYSTEM AND METHOD FOR HOLOGRAPHY-BASED FABRICATION

摘要

A system and method may utilize holography to facilitate fabrication techniques such as 3D printing and lithography. The system may include a light source, a hologram of an original object or lithographic pattern recorded in a holographic medium, and a target such as a reservoir of photosensitive material or a photosensitive material attached to a substrate. Illuminating the hologram with the appropriate light source may cause a holographic image of the original object or lithographic pattern to form on the photosensitive material within the reservoir or on the substrate. Formation of the holographic image may result in the formation of a new object from the photosensitive material, or may facilitate removal or retention of photosensitive material as part of a lithographic process.

主权项

1. A system comprising:
a substrate that supports a photosensitive material; a hologram on which a lithographic pattern is recorded, wherein the hologram is positioned relative to the substrate; a light source tuned to the photosensitive material such that, in response to impingement of light from the light source on the hologram, a holographic image of the lithographic pattern is projected onto the photosensitive material.
