摘要： PROBLEM TO BE SOLVED: To provide a single-sensor stereoscopic image acquisition device for acquiring stereoscopic images without considerably enlarging the size of the device.SOLUTION: The device is based on the Wheatstone principle. Angles of mirrors (M1, M2, M3, M4) are adjusted to form right and left stereoscopic images of a scene on a sensor with a region (IR) interposed between the two images. A slot is formed between internal mirrors. On one hand, structured light or pulse light is passed and, on the other hand, the structured light or pulse light once reflected on an object of the scene is passed. The device further comprises an optical component (AL) related to a slot (Sl) and a lens system (LS) so as to form an image, on the region (IR), from the reflected structured light or pulse light.

摘要： The invention relates to a Fresnel lens. Each refractive structure of the lens is defined by two surfaces, the second surface creates a second angle (ß) with the normal on the plane of incidence (P). At least two refractive structure area are provided, wherein the second angle (ß) is equal to the entrance angle (thetaint) of a beam. Each first surface refracts the light according to a direction which is parallel to or which is not parallel to the axis of the lens according to the area in question. The invention also relates to a system comprising a folding mirror and a Fresnel lens wherein the second angle is equal to the entrance angle of a parasitic ray obtained by reflection on the Fresnel lens and subsequently on the mirror. The invention further relates to a screen and to a corresponding overhead projection device.

摘要： The device has external mirrors (M'1, M'2) and internal mirrors (M'3, M'4) associated with a lens system (SL) to form left and right stereoscopic images of a scene on an image sensor (C). The mirrors are adjusted angularly such that the images are formed on the image sensor so as to leave a zone free between the images. A slit (F) is formed between the internal mirrors to allow structured/pulse light to pass through when the light is reflected on objects of the scene. Optics (AL) is associated with the slit, and the system forms an image on the zone from the structured/pulse light.

摘要： The lens has two prisms (28, 40) in one zone, each including two sides (30, 32), and a prism (34) with two sides (36, 38), in another zone. Angle between the sides (32, 38) and a main axis (AA`), is greater than an angle between the sides (30, 36) and the axis. The side (32) collimates an incident ray (R1) by reflecting the ray parallel to the axis. The side (38) reflects an incident ray (R2) along a direction different from the axis. An independent claim is also included for a projection display device including a Fresnel lens.

摘要： In one embodiment, it is proposed a method for encoding a light field content. The method is remarkable in that it comprises: - obtaining, for a set of light rays (401) associated with said light field content, four coordinates per light ray from a two planes parametrization (2000; 402, 403) of said light field content; - obtaining (2001), for each light ray from said set, two coordinates from said four coordinates, corresponding to a projection of said light rays from said set onto a plane (404, 405, P) perpendicular to two planes used in said two planes parametrization, defining points in a first 2D ray diagram (?(?1, ?2), ?(?1, ?2)); - applying (2002) a discrète Radon transform on said first 2D ray diagram (?(?1, ?2), ?(?1, ?2)) that delivers lines of interest in said first 2D ray diagram; - encoding (2003) said lines of interest into encoded lines of interest; and - storing (2004) said encoded lines of interest.
