An illumination apparatus comprises a first substrate, an optical structure, an array of light emitting elements disposed on the first substrate and between the first substrate and the optical structure, and a mask comprising a plurality of apertures therein. The optical structure is configured to receive light emitted by the array of light emitting elements, direct the received light into a direction away from the first substrate, direct at least some of the light which has been directed away from the first substrate back towards the first substrate, and direct at least some of the light which has been directed back towards the first substrate through the plurality of apertures of the mask.

A ladar transmitter that transmits ladar pulses toward a plurality of range points in a field of view can be controlled to target range points based on any of a plurality of defined shot patterns. Each defined shot pattern can be instantiated to identify various coordinates in the field of view that are to be targeted by a ladar pulses. A processor can process data about the field of view such as range data and/or camera data to make selections as to which of the defined shot patterns should be selected over time.

A camera includes a housing, a light source positioned within the housing, and a light-refracting apparatus. The light-refracting apparatus comprises a collimator shaped to collimate light emitted by the light source, and a lens comprising an at least partially concave light-emitting surface positioned to receive light collimated by the collimator and shaped to disperse the collimated light. The light-refracting apparatus is arranged to cause the dispersed light to be transmitted from within the housing into a field of view region of the camera.

A disinfection device includes: a container having a wall that defines a chamber for containing liquid therein; and a light source for transmitting disinfection light to the liquid. The light source is in a spatial relationship with the container so that a distance between the light source and the first light receiving surface of the liquid remains unchanged regardless of a volume of the liquid.

Broadly speaking, embodiments of the present techniques provide apparatus and methods for generating a three-dimensional (3D) representation of a scene (also known as 3D sensing) using a time-of-flight imaging system. In particular, the present techniques provide an apparatus comprising a time-of-flight imaging camera system that emits illumination having a spatially-nonuniform intensity over afield of view of the sensor that is moved across at least part of the field of view of a sensor using an actuation mechanism.

Systems and methods which provide a high-throughput point source light coupling structure implementing a condenser configured according to one or more condenser configuration rules are described. Embodiments of a high-throughput point source light coupling structure utilize a birefringent plate configuration in combination with a condenser and point source to provide a light coupler structure for a birefringent-static-Fourier transform interferometer implementation. According to some examples, the optical axis of a first and second birefringent plate of a birefringent plate configuration are not in the same plane. A condenser of a high-throughput point source light coupling structure of embodiments is provided in a defined (e.g., spaced, relational, etc.) relationship with respect to the point source and/or a camera lens used in capturing an interference pattern generated by the light coupling structure. High-throughput point source light coupling structures herein may be provided as external accessories for processor-based mobile devices having image capturing capabilities.

A method of making an integrated depth sensor window lens, such as for an augmented reality (AR) head set, the depth sensor window lens comprising a sensor lens and an illuminator lens separated by an opaque dam. The method uses a two-shot injection molding process, a first shot comprising an optically clear polymeric material to form the sensor lens and the illuminator lens and the second shot comprising an opaque polymeric material to form the separator of the two.

A rotationally shift invariant and multi-layered array system for full-field of view and/or photon collection by 4pi steradian field of view. In the system, all of the incoming light (i.e., light from all directions), in a solid angle of 4pi steradians, is focused inside the optics. The optics have a spherically shift invariant structure, providing rotational shift invariance. The system comprises a nontraditional use of the Gabor Superlen and is a configuration of multiple microlens array shell structures with concentrically arranged bulk optical components. Examples of such bulk optical components include Luneburg lenses, micro-structured surfaces, a single lens, a plurality of single lenses, ball lenses, metalenses, diffractive optical elements, and magnetic lenses. In an embodiment, the Gabor Superlens (i.e., microlens array) is planar. In an embodiment, no moving parts are required for the system to achieve truly full-field of view imaging and/or photon collection by 4pi steradian field of view.

This invention relates to an insect detection device comprising a sensing device. The sensing device comprises an optical source configured to emit an optical beam; a first lens group configured to collimate the optical beam to form a beam width of a first predetermined range and a beam height of a second predetermined range; a second lens group configured to collect the optical beam N from the first lens group and arranged apart from the first lens group defining a sensing zone; an optical detector configured to receive the beam from the second lens group and translate the beam to electrical signals; and a processing unit configured to switch on the optical source and receive the electrical signals from the optical detector.

An optical numerical computation device relates light from a plurality of light sources to calculate an arithmetic solution. The optical numerical computation device includes input circuitry, pre-calculation circuitry, calculation circuitry, a light collection cavity, and a plurality of light computation components. The pre-calculation circuitry and calculation circuitry cause light sources to emit light representing the values of input operands, which is subsequently related within the light collection cavity. Sensors then generate resultant outputs at values indicative of the sensed light value. The respective wavelengths of light used may be associated with an operand arithmetic sign or an order of magnitude.
