Abstract
A method of printing an image of a three-dimensional object includes printing multiple dots of a colored ink to form an image of the object and printing dots of a transparent ink having a refractive index greater than 1 within the image. The dots of transparent ink local alter the path length of light that shines through the image to create phase variations on the image.
Claims18
A method of printing an image of a three-dimensional object, the method comprising:
- printing multiple dots of a colored ink to form an image of the object;
- and
- printing dots of a transparent ink having a refractive index greater than 1 within the image, wherein the dots of transparent ink local alter the path length of light that is emitted from the image to create phase variations on the image.
A method of printing an optical element on a two-dimensional surface, the method comprising:
- printing a layer of transparent ink having a refractive index greater than 1 in a pattern on the surface;
- and
- controlling the local optical path length of light that travels though the transparent ink, such that the phase of light reflected by or transmitted through the ink on the surface is altered in a predetermined manner.
