摘要： An optical device for forming a stigmatic image of a laser source positioned at a predetermined point is intended to illuminate a reflecting surface while also providing a separation between the beam emerging from the source and the beam reflected from the surface. The device comprises a cube placed against a converging lens, the dimensions of the assembly thus formed being such that the cube face remote from the lens passes through a Weierstrass point of the spherical refracting surface formed by the lens. The laser source is positioned at the Weierstrass point. The cube is formed by two prisms cemented together, the interface being treated so as to have a polarization-separating effect.

摘要： The optical head in a data carrier recording-reading device comprises a semiconductor laser source. A lens makes it possible to focus the beam from this source. A polarization beam splitter makes it possible to deflect the beam reflected by this carrier towards a group of photodetectors. According to the invention the splitter is an isosceles prism, which serves as an anamorphotic-splitting means. A quarter-wave plate is bonded to one of the faces of the prism. A planoconvex lens can also be bonded to the other face of the prism upstream of the photodetector.

摘要： Optical device for giving access to a track carried on a moving data carrier incorporating a moving element comprising a galvanometric mirror and a focusing objective movable relative to the data carrier and a fixed light energy source incorporating at least one laser emitter. Magnifying optical means of the afocal type are also inserted between the moving element and the light energy source. The magnification is sufficient to ensure that the beam emerging from the optical means completely covers the entrance pupil of the objective. As a result of this arrangement, the beam of light reaching the moving element remains a beam of parallel rays, no matter what the position of said element relative to the light energy source.

摘要： A device makes it possible to eliminate the imbalance of a deviating mirror of an optical system which illuminates a data medium or support when that mirror is subject to rapid displacement. The imbalance is cancelled by the use of a photodetector device which receives the light reflected by a reflecting element positioned around the objective of the optical system which illuminates the medium. A control device then makes it possible to control the position of the mirror based upon the light given off by the reflecting element.

摘要： The present invention relates to optical memories for storing data on the surface of an information-supporting medium including pre-formatted patterns. Such a memory may constitute a random access mass memory, and it may be read/write memory or it may be a write-once memory. The operations of writing to the memory and reading from the memory are based on the optical interaction which occurs at the point of impact of an incident optical beam which causes local changes in optical characteristics which are representative of the data when data is being written, and which produce optical modulation detectable by photoelectric means during data reading. The invention provides an optical memory in which the illumination mode common to reading data and to detecting pre-formatting patterns is modified in order to allow for operation in a standby mode or in order to delete areas reserved for storing data, for example.
摘要翻译：本发明涉及用于在包括预格式化图案的信息支持介质的表面上存储数据的光存储器。这样的存储器可以构成随机存取大容量存储器，并且其可以是读/写存储器，或者它可以是一次写入存储器。写入存储器和从存储器读取的操作基于在入射光束的冲击点处发生的光学相互作用，该入射光束在数据被写入时代表数据的光学特性的局部变化，以及其在数据读取期间产生可由光电装置检测的光调制。本发明提供了一种光学存储器，其中修改了读取数据和检测预格式化模式共同的照明模式，以便允许例如在备用模式下操作或为了删除用于存储数据而保留的区域。
