A communication device for a vehicle which can transmit information in the form of light signals to other road users, wherein the communication device has at least one light source from which light emerges when operating the communication device, and controllable light influencer which selectively deflect or reflect or shade at least a portion of the light emanating from the at least one light source such that the at least one portion of the light exits the communication device as a light signal, or wherein the communication device comprises an array of light sources that can selectively generate light that at least partially emerges as a light signal from the communication device.

A light outputting apparatus includes a first light outputting section and a second light outputting section. The first light outputting section includes a first light source, a first collimator lens, and a first optical element that widens light having passed through the first collimator lens, and the second light outputting section includes a second light source, a second collimator lens, and a second optical element that widens light having passed through the second collimator lens. The first light outputting section and the second light outputting section are so disposed that a first optical path and a second optical path intersect each other at a point on upstream optical paths of the first and second optical elements, and that part of the light outputted from the first light outputting section and part of the light outputted from the second light outputting section overlap with each other.

There is provided an illumination system of a navigation device including a light beam shaping optics, and a first light source and a second light source having different characteristics. The light beam shaping optics is used to shape light beams emitted by the first light source and the second light source to illuminate a work surface with substantially identical incident angles and/or beam sizes.

A panoramic sensing apparatus, comprising: a Fresnel lens system (110) and a light sensing device (120). The Fresnel lens system (110) comprises a composite Fresnel lens (111) in a shape of a frustum, at least one of an inner surface and an outer surface of a sidewall of the frustum being a tooth surface; at least two Fresnel units are distributed on said tooth surface. The light sensing device (120) is used for sensing light rays converged by the Fresnel lens system (110). As the composite Fresnel lens in the shape of a frustum is employed for sensing boundaries of a detection range, in the case where lens areas are the same as a whole, a larger detection range may be obtained, or light energy from each direction may be collected. Further, compared with a composite Fresnel refraction surface arranged on a spherical surface or on a spherical polyhedron, the composite Fresnel refraction surface which is arranged on a sidewall of a frustum involves lowered processing difficulty, and accordingly improved precision and defect-free rate.

Systems, devices, and methods of manufacturing optical engines and laser projectors that are well-suited for use in wearable heads-up displays (WHUDs) are described. Generally, the optical engines of the present disclosure integrate a plurality of laser diodes (e.g., 3 laser diodes, 4 laser diodes) within a single, hermetically or partially hermetically sealed, encapsulated package. Such optical engines may have various advantages over existing designs including, for example, smaller volumes, better manufacturability, faster modulation speed, etc. WHUDs that employ such optical engines and laser projectors are also described.

A time of flight based depth detection system is disclosed that includes a projector configured to sequentially emit multiple complementary illumination patterns. A sensor of the depth detection system is configured to capture the light from the illumination patterns reflecting off objects within the sensor's field of view. The data captured by the sensor can be used to filter out erroneous readings caused by light reflecting off multiple surfaces prior to returning to the sensor.
