Apparatus and methods for controlling a three-dimensional optical field |
摘要 |
The present invention provides an apparatus for controlling a three-dimensional optical field. The apparatus includes a light-emission device and a set of zoom elements. The light-emission device emits a light. The set of zoom elements are disposed in front of the light-emission device, and focus the light from the light-emission device. |

1. An apparatus for controlling a three-dimensional optical field, comprising:
a light-emission device emitting a light for projecting an original light shape; and a set of zoom elements disposed in front of the light-emission device, and focusing the light emitted from the light-emission device and along a light axis, and passing therethrough to project the light onto an external object, wherein: the light-emission device has a plurality of portions, and each of which corresponds to a single one of the set of zoom elements; the set of zoom elements comprise a plurality of first zoom elements, and each of the set of zoom elements includes a liquid lens; the external object has a first and a second portions which are separated by a specific distance along the light axis; and the light passing through the set of zoom elements is projected onto the first portion to form a first sub-shape on the first portion and projected onto the second portion to form a second sub-shape on the second portion, the first and the second sub-shapes form a combined light shape when observed along the light axis, and the combined light shape has a contour essentially free from a distortion. |
