A projection device includes at least one projection module and at least one adjusting structure. The projection module has an optical axis and is adapted to emit an image beam. The image beam is transmitted to a projection target to form a projection image. The adjusting structure includes a base and an adjusting component. The adjusting component is rotatably connected to the base along a first axis, and the projection module is rotatably connected to the adjusting component along the optical axis. The adjusting component and the projection module are adapted to rotate along the first axis such that the projection image moves vertically, and the projection module is adapted to rotate along the optical axis such that the projection image rotates.

Projection device

An optical waveguide apparatus including an optical waveguide element and an optical recycling element is provided. The optical waveguide element includes a first surface and a second surface opposite to the first surface. The first surface or the second surface includes an optical structure. An incident light enters the optical waveguide element via the first surface and is transmitted to the second surface. The optical recycling element is disposed on the second surface of the optical waveguide element. The incident light is transmitted to the optical recycling element via the second surface. The optical recycling element changes a transmission direction of the incident light to generate a recycled light. The recycled light enters the optical waveguide element via the second surface and is transmitted to the first surface.

Optical waveguide apparatus and display

A projection apparatus including an image device and an illumination system is provided. The image device is configured to convert an illumination beam into an image beam. The illumination system includes an illumination light source, a diffusion device and a light uniform device. The illumination light source provides the illumination beam. The illumination beam is transmitted to the image device through the diffusion device and the light uniform device sequentially. The image beam leaves the projection apparatus and converges at a stop. The stop is located outside the projection apparatus.
