An illumination device including a light source and a reflector with a pair of vertically opposed symmetrical reflective surfaces and a pair of horizontally opposed symmetrical reflective surfaces. Each of the vertically and horizontally opposed symmetrical reflective surfaces includes a concave region positioned proximate a light source, and a convex region positioned distal the light source. The pairs of vertically opposed symmetrical reflective surfaces and horizontally opposed symmetrical reflective surfaces of the reflector redistribute light emitted from the light source such that the illumination device outputs a field of illumination having a substantially uniform intensity of light.

An infrared zoom illuminating device includes a lens holder, a curvedly-grooved cylinder sleeved on the lens holder, an infrared emitter fixed to the lens holder, a condenser lens group fixed to the lens holder, a protective glass fixed to the lens holder, the condenser lens group located between the infrared emitter and the protective glass, and a first moving lens group and a second moving lens movably connected to the lens holder and arranged between the condenser lens group and the protective glass. The condenser lens group condenses the infrared light emitted by the infrared LED to prevent light loss during zooming process. Straight grooves and curved grooves define moving distance of the first and second moving lens groups to achieve continuous zooming. The limit ring restricts the axial movement of the curvedly-grooved cylinder to ensure the stability of rotation of the curvedly-grooved cylinder.

The present invention relates to a lens for eye-tracking applications. The lens comprises a first protective layer, arranged to face towards the eye to be tracked when the lens is used for eye- tracking. It also comprises at least one light source, at least partly arranged in the first protective layer, arranged to emit a first light from the first protective layer in a direction towards the eye. Moreover, it comprises at least one image capturing device, at least partly arranged in the first protective layer, arranged to receive the first light within the first protective layer. The lens further comprises an absorptive layer, arranged on the far side of the first protective layer seen from the eye to be tracked when the lens is used for eye-tracking, adapted to be absorptive for wavelengths of the majority of the first light.

An IR illuminator provides infrared radiation for a digital camera that includes a camera lens including a camera field of view; also including equidistant mounting substrates arranged adjacent to the digital camera with IR LEDs mounted to each mounting substrates and a cover lens positioned over the IR LEDs. The free-form cover lens shape facilitates an emitted radiation emission pattern but prevents visible light reflectivity into the camera lens such that the IR radiation emission pattern has an asymmetric field of view. Two IR illuminators near the camera are angled away from the camera optical direction. The cover lens may be a Fresnel lens, may include a diffractive layer or a collimator to shift radiation emitted from the LED towards an asymmetric distribution.

A transmitter of a wireless power transfer and data communication system comprising a transmitter system including a transmitter housing, one or more high-power laser sources, a laser controller, one or more low-power laser sources, one or more photodiodes, a beam steering system and lens assembly, and a safety system. High-power and low-power beams are directed to corresponding receivers and transceivers of a transceiver system inside a remote receiver system by the controller and the beam steering system and lens assembly. Low-power beams include optical communication to the transceiver system. The photodiodes of the transmitter system receive optical communication from the transceiver system. Low-power beams are co-propagated with and in close proximity to high-power beams substantially along an entire distance between the transmitter housing and the receiver system. The safety system instructs the controller to reduce the high-power sources in response to detected events.

A vehicle trim assembly includes a trim component having an interior facing surface and an exterior facing surface opposite the interior facing surface, a lens assembly overmolded into the trim component, the lens assembly including an optical surface positioned adjacent to the exterior facing surface of the trim component, and a sensor module including a sensor housing enclosing a sensor, the sensor module joined to the trim component and the lens assembly.

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.

An optical module includes: an infrared light emitter configured to emit infrared light; an infrared light receiver configured to receive the infrared light emitted from the infrared light emitter and generate a signal based on an amount of the received infrared light; a touch interface arranged between the infrared light emitter and the infrared light receiver, and configured to reflect the infrared light emitted from the infrared light emitter toward the infrared light receiver, and change an amount of the reflected infrared light as a touch input occurs; and a visible light emitter configured to emit visible light toward the touch interface such that the visible light is emitted outside the optical module by passing through the touch interface.

An eye tracking device includes a substrate comprising a first substrate portion and a second substrate portion intersecting with the first substrate portion, an infrared light emitting element on the first substrate portion, and an image acquisition element on the second substrate portion. The infrared light emitting element is configured to emit infrared light to a user's eyeball. The image acquisition element and the infrared light emitting element are non-coplanar. The image acquisition element is configured to receive and sense the infrared light reflected by the eyeball for imaging.

The disclosure provides for a free-space optical communication system that includes a first lens group, a field corrector lens, and a second lens group. The first lens group is configured to receive light received from a remote free-space optical transmitter. The first lens group has a first focal plane. The field corrector lens is positioned between the first lens group and the first focal plane of the first lens group and positioned closer to the first focal plane than the first lens group. The first lens group also is made of material having an index of refraction of at least 2.0, and has a second focal plane. The second lens group is positioned at the second focal plane of the field corrector lens and is configured to couple light to a sensor.
