Image rearranging lens and projection apparatus

摘要

An image rearranging lens and a projection apparatus are provided. The image rearranging lens is used to rearrange a plurality of sub images provided by an image source and arranged along an arranging direction. The image rearranging lens includes a plurality of lens groups arranged along the arranging direction. Each of the sub images is imaged on a corresponding lens group. Optical axes of the lens groups are not aligned to each other along the arranging direction. The optical axis of each of the lens groups and the optical axis of the neighboring lens groups have an offset along a direction perpendicular to the arranging direction.

主权项

1. An image rearranging lens for rearranging a first image provided by an image source, the first image comprising a plurality of sub images arranged along a first direction, the image rearranging lens comprising:
a plurality of lens groups arranged along the first direction, each of the lens groups being suitable for propagating one of the sub images along a propagating direction, the lens groups being suitable for rearranging the first image comprising the sub images arranged along the first direction into a second image comprising the sub images arranged along a second direction, the second direction being different from the first direction and different from the propagating direction, and an offset existing between two adjacent lens groups along the second direction.
