摘要： An optical source comprising a semiconductor laser having an emissive junction and optical means for the anamorphosis of the beam emitted by said laser. The optical means comprise a concave holographic diffraction grating. The location of the recording sources of said grating and of the semiconductor laser and their wavelength are such that said grating makes a stigmatic image of said laser with a good aplanetism. The angle of diffraction is selected so as to reduce the non-isotropy of the beam emitted by the semi-conductor laser.

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.

摘要： A UHF phase shifter including a UHF waveguide having an electrooptical element lying between two elements 3 and 4 made of materials which have permittivity higher than that of the electrooptical element. An electric polarization field is applied for controlling the electrooptical element and a UHF line is inserted into the element. The control of the orientation of the molecules of the electrooptical element allows for a variation of the index of the element as seen by the field of a UHF wave.

摘要： Device for creating optical delays in which several secondary optical paths are provided and placed in series and in shunt with a main optical path. Access to the secondary optical paths is obtained via switches that are placed along the main optical path. The length of the delay circuits are in a geometric progression whose common ratio has the value of two. Depending upon the switching states of the switches it is therefore possible to obtain a series of equal distant delays with a relatively small number of switches.

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 Switch is disclosed which makes it possible to optically connect at least one of the circuits of a group of input circuits to at least one circuit of a group of output circuits. A photosensitive medium is illuminated by parallel beams from a matrix of input circuits which beams are then defracted on layers written in the medium and then reach one of the circuits of the matrix of photoreceiver circuits. The layers are written by interference of two beams whose wavelengths differ from that of input beams with the wavelength of the input beams being out of the spectral sensitivity range of the photosensitive medium.
