    摘要： An optical system for image projection, particularly for projection devices of the “head-mounted” type, includes a display, an optical system for focusing an image formed by the display, and a light guide having an extended body, with two opposite, longitudinal, plane and parallel faces, and opposite ends which define first reflecting surface for coupling into the light guide and second reflecting surface for extracting the image from the light guide. Each light ray which propagates through the light guide undergoes at least three internal total reflections on the parallel plane faces of the light guide. At least a surface of the focusing optical system is a portion of a surface free of rotational symmetry axes. Moreover, the two reflecting surfaces of the light guide are portions of surfaces free of rotational symmetry axes. Finally, the inlet pupil of the light guide coincides with the outlet pupil of the focusing system.

    摘要： Multifunctional optical sensor, comprising a matrix of photodetectors of the CCD or CMOS type, having a sensitive area divided into sub-areas, each of which, individually or combined with others, is dedicated to a specific function of monitoring the scene or measuring environmental parameters. The optical sensor comprises a matrix of microlenses, each of which is set to focus the radiation coming from a portion of solid angle on the associated photodetector or cluster of mutually contiguous photodetectors. Each function is associated to a single microlens or to a single subgroup of mutually contiguous microlenses or to multiple, not mutually contiguous microlenses or to multiple, not mutually contiguous subgroups of microlenses. The angular separation between the central directions of the portions of solid angle subtended by adjacent photodetectors or adjacent clusters of photodetectors is not constant within the matrix.

    摘要： An optical element for the projection of a light beam comprises a solid body (1) of transparent material in which is formed a cavity (13) able to receive a light source (10), the cavity (13) extending along the principal axis (z) of the transparent body (1) and being delimited by a radially inner surface (3) and a terminal surface (2) of the transparent body (1). The surfaces (2, 3) are able to receive separate respective portions (I, II) of the light flux generated by the source (10). The transparent body (1) further has a radially outer surface (4) which surrounds the radially inner surface (3). The radially outer surface (4) reflects the portion of the light flux (I) coming from the radially inner surface (3) along a direction substantially parallel to the principal axis (z). The transparent body (1) has, on the opposite side, a central surface (6) and an annular surface (5) surrounding the central surface (6), able to receive that portion (II) of the light flux and the reflected portion of the light flux (I) respectively and to transmit these light flux portions (I, II) in directions having predetermined orientations with respect to the principal axis (z). At least one of the surfaces (2, 3, 5, 6) is rotationally asymmetric with respect to the principal axis (z) of the transparent body (1). The surfaces (2, 3, 5, 6) cooperate in such a way as to shape the overall light flux (I, II) emitted by the central and annular surfaces (6, 5) into a light intensity distribution having different divergences in two directions perpendicular to one another and to the principal axis (z).

    摘要： A module for projecting a light beam comprises a light source and a substantially flat support surface on which the source is arranged in a manner such as to emit light from only one side of the surface, and a reflector for reflecting the light emitted by the source. The reflector comprises a curved reflecting surface which extends on one side of the support surface, has a concavity facing towards the support surface, and can reflect the light coming from the source in a principal direction substantially parallel to the support surface of the source. An optical device for a module according to the invention and a vehicle front light assembly comprising a plurality of modules according to the invention form further subjects of the invention.
