摘要:
A projection lens for projecting an image beam is provided. The image beam is converted by a light valve from an illumination beam irradiating the light valve. The projection lens includes a first lens group, a second lens group, and a third lens group. The first lens group is disposed on a transmission path of the image beam, and has a first optical axis. The second lens group is disposed on both a transmission path of the illumination beam and the transmission path of the image beam, and between the light valve and the first lens group. The second lens group has a second optical axis. The second optical axis is inclined with respect to the first optical axis. The third lens group is disposed on the transmission path of the image beam, and between the first lens group and the second lens group. A projection apparatus is also provided.

摘要:
A projection system used in a vehicle including a projection apparatus, a projection screen, and an image correction module is provided. The projection apparatus provides an image beam. The projection screen receives the image beam. The image beam forms an image on the projection screen. The projection screen is a non-flat plane. The image correction module corrects the image beam to compensate a distortion of the projected image based on the surface contour of the image screen.

A vehicular projection system (100) including a projection apparatus (110), a beam splitting module (120), and two projection screens (130a, 130b) is provided. The projection apparatus (110) provides at least one image light beam (A+B). The beam splitting module (120) divides the image light beam into a first image light beam (A 1 ) and a second image light beam (B 2 ). The two projection screens (130a, 130b) receive the first image light beam (A 1 ) and the second image light beam (B 2 ) respectively. Each of the first image light beam (A1) and the second image light beam (B2) respectively forms an image on one of the two projection screens (130a, 130b) corresponding thereto.
