摘要： This device comprises an optical source emitting a single-wavelength light beam. An index grating has been recorded in a holographic device by the interference of two plane light beams, both being beams at a single wavelength with one and the same determined value and being concurrent in the holographic device. The holographic device is illuminated by the light beam and delivers a single-wavelength beam whose radiation pattern has a limited angular passband. The wavelength of the reading beam may be different from that of the recording beams. Its orientation is then different from that of the beams.

摘要： Disclosed is an image projector wherein the illumination of an LCD matrix screen is done by means of two polarized beams coming from a same light beam that has no particular direction of polarization. The two polarized beams are obtained by a polarization separator whence these two polarized beams emerge with a square section. On the one hand, each polarized beam goes through at least two juxtaposed convergent lenses by which it is converted into two sub-beams which project their illumination spot on the matrix screen and, on the other hand, each convergent lens has a surface with a shape that is homothetic with the shape of the matrix screen. The luminous efficiency is thus improved through the matching of the shape of the section of the non-polarized light beam with that of the matrix screen.

摘要： Disclosed is an image projector in which a spatial modulation of light is carried out on the two orthogonal components of polarization of light in order to increase the luminous efficiency of the projector. The image projector of the invention includes a light source, a projection screen, a splitter of polarizations splitting the light into two polarized beams having complementary polarizations, two mirrors reflecting the two polarized beams, firstly so as to give them opposite directions and superimpose them on one and the same axis on which a spatial light modulator is positioned and, secondly, to make them pass again through the polarization splitter by which they are superimposed on one and the same axis with one and the same direction and oriented towards the projection screen and/or the light source as a function of their modulation by the spatial modulator.

摘要： Disclosed is an image projector of the type in which an LCD matrix screen is illuminated by two polarized beams after 90.degree. rotation of the direction of polarization of one of these two beams. Each of the two polarized beams is reflected at least once towards an optical axis on which the matrix screen is centered and at least once again towards the matrix screen. Furthermore, the image projector has means to make each beam polarized, so that each polarized beam forms an image of the light source before illuminating the matrix screen. The two polarized beams may thus be oriented towards the matrix screen in forming a small angle with one another, thus enabling the use of a projection objective with a small aperture.
摘要翻译：公开了一种这种类型的图像投影仪，其中在这两个光束之一的偏振方向90度旋转之后，LCD矩阵屏幕被两个偏振光束照射。两个偏振光束中的每一个至少一次朝向矩阵屏幕中心的光轴反射，并且至少再次朝向矩阵屏幕反射。此外，图像投影仪具有使每个光束偏振的装置，使得每个偏振光束在照射矩阵屏幕之前形成光源的图像。因此，两个偏振光束可以朝着矩形屏幕定向成彼此形成小角度，从而能够使用具有小孔径的投影物镜。

摘要： A laser source is disclosed with coherent recombination of N spatial monomode laser beams having N phase shifters controlled by a phase-lock device (3). The phase-lock device has an optical device (30) capable of taking at least a portion of each of the N beams. The optical device has an optical element (32) capable of applying a phase deformation, and at least one matrix (M1) of detectors capable of detecting a first image (im) of a wave surface corresponding to the N beams. The matrix (M1) of detectors also detects a second image (imd) deformed by the optical element (32). Processing means (31) are provided for processing the first and second images. The processing means are configured so as to measure the phase pistons between on the sub-pupils (spj) corresponding to the N beams and to apply phase corrections c(φ) to each of the N beams, by means of said N phase shifters so as to minimize the phase pistons.
