According to an aspect of the present invention to accomplish the above and other objects, a color sensor module comprising a color sensor for detecting a surrounding color condition, and a concave lens located in front of the color sensor can ensure an amount of light reaching the color sensor, thereby obtaining more accurate color condition information, regardless of the incident angle.

The present disclosure discloses an optical module package structure and method thereof. The optical module includes a substrate, a shield, a photosensitive unit and a cover. The shield is disposed on the top of the substrate and forms a first housing space with the upper surface of the substrate. The photosensitive unit is disposed on the substrate and located in the first housing space. The shield has a light-receiving part above the photosensitive unit. At least one notch is on the outer surface of the shield. A cushion is disposed on the notch and protrudes on the upper surface of the shield. The cover is disposed on the cushion(s) and kept a constant distance to the upper surface of the shield by contacting with the cushion(s).

A laser-radiation detector is formed from a plurality of layers supported on a substrate. The plurality of layers includes a reflective metal layer and an oriented polycrystalline sensor-layer positioned between the metal layer and the substrate.

A real-time lighting control system of an ecosystem and real-time lighting control method includes a computer device, multiple lighting devices and multiple wireless base stations. The lighting devices and the wireless base stations are arranged in multiple lighting regions of an indoor space. Each wireless base station emits a wireless signal continuously, and controls one or more connected lighting devices when receiving a lighting control signal. The computer device senses the wireless signals continuously, and keeps determining its position at the different time points according to the received wireless signals and the arranged positions of the wireless base stations. Next, the computer selects one of the lighting regions according to space information and the determined positions, and sends the lighting control signal to one of the wireless base stations arranged in the selected lighting region.

An optical sensor, optical system, and proximity sensor are disclosed. An illustrative proximity sensor is disclosed to include a light source and a photodetector including a photo-sensitive area that receives incident light and converts the received incident light into an electrical signal. The light source and photodetector are positioned diagonally relative to one another, thereby enabling the devices to be positioned closer together on a body or substrate.

A wireless optical communication receiver is provided. The optical receiver includes an arrangement of wavelength shifting fibres preferably encased within a protective shroud. The wavelength shifting fibres provide an efficient method for capturing photons of light that strike them. Photons may strike the fibres as they first pass through a clear lens in the shroud or may strike the fibres after they are concentrated and focused by an embedded ring or hyperbolic mirror. The wireless optical receiver may be attacked to a mobile vehicle in order to facilitate teleoperation of that vehicle.

A system and a method for transporting high luminous intensity light from at least one luminaire to a destination area are disclosed. The system may include a light guide that carries light from the luminaire to a plurality of sensors located on a Printed Circuit Board (PCB). The PCB may be attachable anywhere the luminaire is located. According to an aspect, the luminaire is a separate entity from the sensor system. While collecting light rays originating from the luminaire and delivering them to the light sensors, the light guide may perform a plurality of operations to modify the characteristics of the collected light rays. The plurality of operations performed by the light guide on the light rays may support the accuracy and longevity of the light sensors on the PCB. Further, the light guide allows the sensor subsystem to be proximal to or distant from the luminaire.

The present invention relates to a space-based instrument which provides continuous coronal electron temperature and velocity images, for a predetermined period of time, thereby improving the understanding of coronal evolution and how the solar wind and Coronal Mass Ejection transients evolve from the low solar atmosphere through the heliosphere for an entire solar rotation. Specifically, the present invention relates to using a 6U spherical occulter coronagraph CubeSat, and a relative navigational system (RNS) that controls the position of the spacecraft relative to the occulting sphere. The present invention innovatively deploys a free-flying spherical occulter, and after deployment, the actively controlled CubeSat will provide an inertial formation flying with the spherical occulter and Sun.

Optoelectronic modules for proximity determination and ambient light sensing include hybrid optical assemblies configured with multiple field-of-views. The field of view in a region of the hybrid optical assembly can be dedicated to a first detector, while the field of views in another region of the hybrid optical assembly can be dedicated to both the emission of light and ambient light sensing. Embodiments relate particularly to implementation in a mobile phone or other portable electronic devices.

A multi-channel receiver optical subassembly (ROSA) including at least one sidewall receptacle configured to receive and electrically isolate an adjacent multi-channel transmitter optical subassembly (TOSA) is disclosed. The multi-channel ROSA includes a housing with at least first and second sidewalls, with the first sidewall being opposite the second sidewall and including at least one sidewall opening configured to fixedly attach to photodiode assemblies. The second sidewall includes at least one sidewall receptacle configured to receive at least a portion of an optical component package, such as a transistor outline (TO) can laser package, of an adjacent multi-channel TOSA, and provide electrical isolation between the ROSA housing and the TOSA within an optical transceiver. The sidewall receptacle can include non-conductive material in regions that directly or otherwise come into close proximity with the optical component package of the adjacent TOSA.
