Methods, devices and systems that allow three-dimensional printing of material with high resolution are described. One example system includes a two-photon polymerization (TPP) subsystem including a first light source coupled to an optical fiber positioned to deliver a first laser light to a scanning optical device, and an optical projection subsystem comprising a second light source configured to provide a second light to a digital projection device. A dichroic mirror is positioned to receive light corresponding to the first and the second light source, and an objective lens positioned to provide illumination to a target material for 3D printing. The dichroic mirror is configured to allow light from one of the light sources to pass therethrough to the objective lens, and to allow light corresponding to the other light source to be reflected towards the objective lens to enable simultaneous illumination of the target material.

An IR illuminator for providing infrared radiation for a digital camera having a camera lens with a camera field of view, including equidistant mounting substrates arranged adjacent to the digital camera, IR LEDs mounted to each of the mounting substrates, and a cover lens positioned to cover the IR LEDs. The shape of the free form cover lens is such that an emission pattern of radiation is emitted without entering into the camera lens and the emission pattern of IR radiation has an asymmetric field of view. Two IR illuminators adjacent to the camera are tilted at an angle from the camera optical direction. The cover lens may be a Fresnel lens, or include a diffractive layer or a collimator to shift radiation emitted from the LED to an asymmetric distribution.

A camera module includes a housing with an opening and a portion that surrounds the opening, wherein the portion of the housing is transparent to near infrared (NIR) light. A fisheye lens is disposed within the opening such that a portion of the fisheye lens protrudes through the opening. An image sensor is disposed within the housing and optically coupled to the fisheye lens. The image sensor is sensitive to visible light and NIR light. A plurality of NIR light emitters is disposed within the housing. The NIR light emitters are configured to emit NIR light through the NIR-transparent portion of the housing. The NIR-transparent portion of the housing may include a light-diffusing structure, such as a pattern of microlenses formed on an inner surface of the NIR-transparent portion of the housing, to spread out the NIR light emitted by the NIR light emitters.

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.

A combination comprises at least one lens and at least one prism. The at least one lens and the at least one prism are in an optical path of a corresponding at least one light source. The combination is configured to direct light radiating from the at least one light source toward a projector lens.

Control instructions are transmitted to receivers by modulating light sources to generate light beams that are modulated with digital data streams for inducing control instructions in the light beams. Each light beam is applied to a pixel shaper element of a pixel shaper assembly to produce a light pixel, each light pixel carrying the control instructions of the light beam, each light pixel having a perimeter defined by the pixel shaper element. The pixel shaper assembly combines the light pixels into an image without significant overlap or voids between the light pixels. The light pixels are directed toward a projector lens for transmission toward the receivers. In a receiver, an optical receiver detects a light pixel. A controller decodes the control instructions received in the detected light pixel and uses the control instructions to control a function of the receiver.

A device comprises an enclosure having a rear opening adapted to receive a light beam from a light source, a front opening adapted to emit a modified light beam, and internal walls extending between the rear opening and the front opening. The light beam is modified according to a perimeter of the front opening. A light shaping assembly comprises a two-dimensional array formed of a plurality of such devices, each one of the plurality of devices being adapted to receive a light beam from a corresponding light source.

A light shaping assembly comprises a printed circuit board (PCB) and a two-dimensional (2D) array formed of a plurality of rows, each row comprising a plurality of light sources mounted on the PCB, each light source comprising a pair of supporting pins for mounting the light source on the PCB. The supporting pins of each light source are bent at an angle that is increasing as a function of a distance between each light source and a selected point on the PCB so that light beams emitted by the light sources are collectively directed toward a common target.

An equipment security system includes one or more sensors or optical recording devices disposed on or inside a cargo container. A computing device receives data from the one or more sensors or optical recording devices, determines whether an event has occurred at the cargo container, determines a geofence associated with the cargo container, and selects or configures a dynamic script including instructions that specify whether to begin recording an event occurring at or inside the cargo container, whether to record the event in an overwritable, local memory associated with at least one of the one or more sensors or optical recording devices or the computing device, parameters that govern how data associated with the event will be recorded, and whether to upload the data from the local memory to a remote server.

A light shaping assembly comprises a printed circuit board (PCB), a two-dimensional (2D) array formed of a plurality of rows, each row comprising a plurality of light sources mounted on the PCB, and a Fresnel lens. The Fresnel lens redirects a light beam emitted by each light source at an angle that increases as a function of a distance between each light source and a selected point on the PCB, so that the light beams emitted by the light sources are collectively directed toward a common target.
