Homogenizing module and projection apparatus

A projection apparatus, comprising a light source module, a homogenizing module, a light valve and a projection lens, wherein:

• the light source module is configured to provide a beam;
• the homogenizing module is located on a transmission path of the beam from the light source module, and is configured to convert the beam into an illumination beam, and the homogenizing module comprises an anisotropic diffuser and a homogenizer, wherein:
• the anisotropic diffuser is located on a transmission path of the beam, the beam has a first divergence angle in a first direction and a second divergence angle in a second direction after passing through the anisotropic diffuser, and the first divergence angle is greater than the second divergence angle;
• and
• the homogenizer is located on a transmission path of the beam from the anisotropic diffuser, the homogenizer comprises a plurality of optical elements, and a size of one of the optical elements in the first direction is greater than a size of the one of the optical element in the second direction, wherein the first direction is perpendicular to the second direction;
• 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;
• and
• the projection lens is located on a transmission path of the image beam and is configured to project the image beam.
