Optical module and projection apparatus

A projection apparatus comprising an illumination system, a light valve, an optical module, and a projection lens, wherein

• the illumination system is configured to provide an illumination beam,
• the light valve is located on a transmission path of the illumination beam and is configured to convert the illumination beam into an image beam,
• the optical module is located on a transmission path of the image beam and is configured to increase a resolution of the image beam, and the optical module comprises a base, a first frame, an optical element, and at least one first driving assembly, wherein
• the first frame is disposed in the base, and the first frame comprises a first body and a pair of first shaft portions, wherein the pair of first shaft portions extend outward from the first body, and the first body comprises a pair of first inner folded edges,
• the optical element is disposed between the pair of first inner folded edges, and
• the at least one first driving assembly and the optical element abut against two opposite sides of one of the pair of first inner folded edges, respectively, and the at least one first driving assembly is configured to drive the first body to swing relative to the base by taking the pair of first shaft portions as a rotating shaft, and
• the projection lens is located on the transmission path of the image beam and is configured to project the image beam, wherein the optical module is disposed between the light valve and the projection lens.
