Fluorescent Contact Imaging for In-Process Print Sensing |
| 摘要 |
System for visualization of conformal contact. The system visualizes conformal contact between a patterned stamp and a transparent impression surface. A patterned stamp is provided that includes a fluorescent structure for contact with the impression surface. A source of UV light is provided for transmission through the transparent impression surface to interact with the fluorescent structure to generate visible light re-emitted by the fluorescent structure. An imaging system captures the visible light to form a high-contrast image of an area of conformal contact between the patterned stamp and the impression surface. The high-contrast image comprises bright and dark regions representing contact and no contact respectively. |

1. System for visualization of conformal contact between a patterned stamp and a transparent impression surface comprising:
a patterned stamp including a fluorescent structure for contact with the impression surface; a source of UV light for transmission through the transparent impression surface to interact with the fluorescent structure to generate visible light re-emitted by the fluorescent structure; and an imaging system for capturing the visible light to form a high-contrast image of an area of conformal contact between the patterned stamp and the impression surface. |
