摘要： The invention relates to an image projector providing homogeneous lighting of an object to be projected while increasing the light collection efficiency. The projector (1) is comprised of a light source (6) producing a light intended to illuminate an object (2) having a given shape. According to the invention, the projector (1) is further comprised of a housing (7), wherein the light is subjected to multiple diffusions before emerging through an outlet window (9) to illuminate the object (2), and, additionally the shape of the outlet opening (9) is the same as that of the object to be projected. The invention is applicable particularly to television projectors using a liquid crystal screen.

摘要： The invention concerns display panels in particular liquid crystal panels. On account of the natural birefringence of liquid crystals, the contrast is deteriorated when a liquid crystal cell is observed under an oblique incidence. Compensating structures with birefringent media are used for correcting this fault. The compensating structure associated with the liquid crystal cell (10) comprises at least one film (A2)of which the birefringence is induced by the recording of a volume hologram in parallel fringes. The selection of optical axes of birefringence depends only of the orientation of the fringes such that it is easy to produce compensation by uniaxial films inclined relative to the plane of the film.
摘要翻译：本发明涉及显示面板，特别是液晶面板。由于液晶的自然双折射，当在倾斜入射下观察液晶单元时，对比度会恶化。使用双折射介质的补偿结构来校正该故障。与液晶单元（10）相关联的补偿结构包括至少一个薄膜（A2），其通过以平行条纹记录体积全息图而引起双折射。双折射光轴的选择仅取决于条纹的取向，使得易于通过相对于膜的平面倾斜的单轴膜产生补偿。

摘要： The invention relates to a microwave planar antenna whose main lobe is orientable by mechanical means. A microwave antenna is formed by a network of radiating dipoles (2, 16) arranged in a circuit (3, 4, 17, 18) deposited on a substrate (7), and by a ground plane (8). In order to orient said antenna, at least one dielectric sheet (9) is introduced between the network and the ground plane. Said sheet is comprised of diphasing elements (13, 14, 19, 20), moulded in the sheet (9). The displacement of the sheet (9) with respect to the network (2, 16) causes a phase shifting of the dipoles and an orientation of the antenna lobe. Application to microwave telecommunication antennas.
