Claims
- 1. A system for image-scanning a pixel-mask pattern onto a subject, the system comprising:
first and second panels for generating first and second patterns, each pattern comprising a plurality of pixel elements; a first mirror for diverting the pixel elements of the first pattern to align with the pixel elements of the second pattern; a first gradient lens system positioned between the first and second panels and the subject for simultaneously directing the pixel elements to the subject; means for providing relative movement between the first and second panels and the subject to scan the pixel elements across the subject.
- 2. The system of claim 1 wherein the pixel elements of the first pattern are exposed on the subject simultaneously with the pixel elements of the second pattern.
- 3. The system of claim 1 wherein the pixel elements of the first pattern overlap the pixel elements of the second pattern when scanned on the subject.
- 4. The system of claim 1 further comprising:
a pattern reducer positioned between the panel and the gradient lens system for shrinking an effective size of the pixel mask pattern.
- 5. The system of claim 1 wherein the gradient lens system is an array of lenses with a 1:1 image transfer ratio.
- 6. The system of claim 1 further comprising:
third and fourth panels for generating third and fourth patterns, each pattern comprising a plurality of pixel elements; a second mirror for diverting the pixel elements of the third pattern to align with the pixel elements of the fourth pattern; and a second gradient lens system positioned between the third and fourth panels and the subject for simultaneously directing the pixel elements to the subject; wherein the pixel elements from the first and second panels are scanned across a first surface of the subject, and the pixel elements from the third and fourth panels are scanned across a second surface of the subject.
- 7. The system of claim 6 wherein the first and second surfaces are on opposite sides of the subject.
- 8. The system of claim 6 wherein the first and second surfaces are simultaneously scanned onto the subject.
- 9. The system of claim 1 further comprising:
a non-coherent light source for projecting the pattern using the panel.
- 10. The system of claim 1 further comprising:
a computing system for generating the pixel elements and providing the pixel elements to the panel in a predetermined sequence.
- 11. The system of claim 10 wherein the computing system is also used for designing the pattern.
- 12. The system of claim 10 wherein the computing system is also used for adjusting a scale of the pattern.
- 13. The system of claim 10 wherein the computing system is also used for correcting image distortion in the pattern.
- 14. A system for image-scanning a pixel-mask pattern onto a subject, the system comprising:
a point array unit, the unit including:
a panel for generating the pattern, the pattern comprising a plurality of pixel elements; a first lens system positioned between the panel and the subject for directing the pixel elements to the subject; and a second lens system for focusing the pixel elements; and means for providing relative movement between the unit and the subject to scan the pixel elements across the subject.
- 15. The system of claim 14 further including a grating within the point array unit.
- 16. The system of claim 14 wherein the second lens system is a microlens array.
- 17. The system of claim 14 further including a third lens system positioned between the point array unit and the subject for focusing the pixel elements onto the subject.
- 18. The system of claim 14 further including a plurality of point array units for simultaneously scanning a plurality of pixel elements across the subject.
