Abstract: An infrared sensor device for motor-vehicles, designed to detect the presence of an overtaking vehicle, comprising at least two cells sensitive to infrared radiation, placed on one side of the reflecting plate on the outside rear view mirror of a motor-vehicle, behind focusing optics. Each cell emits a signal proportional to the infrared radiation it receives. An electronic circuit emits a global signal proportional to the difference between the signals emitted by the two cells, so that said global signal enables the presence of an overtaking vehicle to be distinguished from that of other vehicles travelling in the opposite direction, as well as avoiding false alarms due to electronic and electromagnetic noise.

Abstract: The radiation beam emitted by a polychromatic source of finite dimension is incident onto an array of microlenses which have the function of converging and dividing the beam into a plurality of microbeams directed towards a matrix containing colored microfilters. Once the microfilters have been passed, the radiation reaches a matrix of microchoppers which can be selected independently from each other by a controller, for generating images.

Abstract: A light concentrator is described, for a device for the conversion of solar radiation into electrical, thermal or chemical energy, capable of conveying the radiation towards a surface of the conversion device. The concentrator comprises at least one portion of Fresnel lens of rotational symmetry, one face of which has a plurality of crests disposed concentrically about a center so as to form a segmented transverse profile of the portion of Fresnel lens. The profile is formed in such a manner that the focal distance of the Fresnel lens is variable in dependence on the radial distance from the center of the lens. The variation of the focal distance is determined such that, when the Fresnel lens is illuminated by polychromatic radiation, the superposition of the distributions of irradiance, produced by the lens at the individual wavelengths constituting the spectrum of the incident radiation, generates a substantially uniform distribution of polychromatic irradiance on the conversion device.

Abstract: 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.

Abstract: An optical device to measure the distance between the device itself and an obstacle/object comprising a unit to emit radiation including an aligned series of sources of radiation coupled to a series of arrangements of lenses to guide the radiation emitted by the sources. An optical acquisition unit comprising a matrix of photodetectors has a field of view including the scene in front of the optical device and including the obstacle. The signals leaving the acquisition unit are sent to a control and processing unit for calculation of the distance from the obstacle. The unit for the emission and conformation of the radiation emits a beam having a transverse section of a form elongated along an axis that is progressively rotated for transverse sections of the beam progressively more distant from the emission unit. In this manner, the distance of the obstacle may be calculated on the basis of the angular position of the section of the beam intercepted by the obstacle, as acquired by said acquisition unit.

Abstract: 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.
