System and methods for accurate measurement and real-time feedback of solar ultraviolet exposure for management of ultraviolet dose. The systems can include a wearable device and a mobile device, the system performing accurate measurement of UV exposure.

Disclosed are an ultraviolet mirror device and a method therefor. The ultraviolet mirror device of the present invention relates to a device that can generate an image obtained by capturing an image of skin in the ultraviolet region. The device can be connected to a portable terminal having a display unit, so as to be used as an ultraviolet mirror. To this end, the ultraviolet mirror device includes an ultraviolet filtering unit provided in a front portion or a rear portion of the lens unit to allow ultraviolet light to pass therethrough and thus enter the image sensor; and an image processing unit providing the portable terminal with multiple digital images generated at a predetermined frame rate per second by the image sensor and thus allowing a moving image to be regenerated in the display unit.

An electronic device may have a display with a cover layer. An ambient light sensor may be aligned with an ambient light sensor window formed from an opening in a masking layer on the cover layer in an inactive portion of the display. To help mask the ambient light sensor window from view, the ambient light sensor window may be provided with a black coating that matches the appearance of surrounding masking layer material while allowing light to reach the ambient light sensor. The black coating may be formed from a black physical vapor deposition thin-film inorganic layer with a high index of refraction. An antireflection layer formed from a stack of dielectric layers may be interposed between the black thin-film inorganic layer and the display cover layer.

An optical filter including a base member having a layer containing near-infrared absorbing fine particles and a dielectric multilayer film, the optical filter satisfying a requirement that, in a wavelength range of 400 nm to 650 nm, an average of transmittance of any of light incident from a direction perpendicular to the optical filter, light obliquely incident at an angle of 30 degrees, and light obliquely incident at an angle of 60 degrees is 45% or higher and lower than 85%; and a requirement that, in a wavelength range of 800 nm to 1,200 nm, an average of optical density (OD value) of any of light incident from the direction perpendicular to the optical filter, light obliquely incident at an angle of 30 degrees with respect to the perpendicular direction, and light obliquely incident at an angle of 60 degrees with respect to the perpendicular direction is 1.7 or higher.

A dual sensor module includes a substrate, a light source, a first encapsulant, a second encapsulant, a photodetector, and an electrode. The light source is disposed on the substrate. The first encapsulant is formed over the light source. The photodetector is disposed on the substrate. The second encapsulant is formed over the photodetector. The electrode is electrically connected to the substrate and is entirely located between the light source and the photodetector. A dual sensing accessory and a dual sensing device having the dual sensor module for detecting optical and electrical properties are also provided.

An image sensor module includes a circuit board, an image sensor, and a turning prism. The circuit board has first and second side sections each extending in a respective plane transverse to a plane of a center section to define a module interior volume. The image sensor has a bottom plane mounted on an inner face of the circuit board within the module interior volume. The turning prism has a mounting surface secured to a top plane of the image sensor. An electronic component arrangement is operatively mounted on the inner face of the circuit board between the image sensor and a circuit board rearward end. A number of wires providing power and data connections to the circuit board are operatively connected to contacts located on the circuit board in the interior volume between the electronic component arrangement and the circuit board rearward end.

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 non-power-driven photometer is provided, the photometer comprising: a body; and multiple narrow angle photoreceivers (narrow angle probes) formed in the body, wherein the multiple narrow angle probes receive light in the atmosphere, which is incident over a range of different azimuth angles, and allow the characteristics of the atmosphere to be analyzed with reference to the relationship between the received light and the azimuth angle of the narrow angle probe corresponding to the received light. According to the present invention, since the photometer is driven without being supplied with power, light intensity measurement can be performed in a short time. Further, since light intensity measurement can be performed with no movement or only a short-distance movement of a vehicle or airplane equipped with the photometer, the problem of errors caused by differences in the time and location of measurement can be prevented.

An optoelectronic module has multiple optical channels each of which includes a respective optical element at a different height within the module. The modules can include channels arranged side-by-side where each channel is covered by a respective cover that is optically transmissive to one or more wavelengths of light emitted by or detectable by the optoelectronic devices in the module. The transmissive covers, which respectively can include one or more passive optical elements on their surfaces, are disposed at different heights within the module.

A display screen includes a first glass substrate including a color filter region and a light shielding region. The light shielding region includes a transparent region at a first position of the light shielding region. The display screen further includes a second glass substrate including a display control circuit. The display control circuit controls display statuses of the color filter region. The display screen also includes a light intensity sensor at a second position of the second glass substrate. The first position and the second position satisfy a preset relative positional correspondence to allow light transmitted through the first position to reach the light intensity sensor.
