| 摘要 |
The invention features an autostereoscopic imaging device comprising n view points comprising a lenticular network (RL1) comprising cylindrical lenses (10) having longitudinal axes parallel to a direction (zz') perpendicular to an optical axis (x'x) of the device. It comprises a cylindrical optical assembly whose longitudinal axis is perpendicular to zz' and to xx'. The lenticular network (RL1) comprises n cylindrical lenses (10). The lenticular network (RL1) and the cylindrical optical assembly (LC1) have a common focusing plane (P) corresponding to a focusing distance ( DELTA ). The absolute value of the ratio between the focal distance of the cylindrical optical assembly and that of the lenticular network is substantially equal to n. The invention also features a projection device, implementing the said imaging device and a projector projecting n elementary flat images and a screen equipped with at least one projection network.
