There is provided an image module package including a substrate, a photo sensor chip, a molded transparent layer and a glass filter. The substrate has an upper surface. The photo sensor chip is attached to the upper surface of the substrate and electrically connected to the substrate. The molded transparent layer covers the photo sensor chip and a part of the upper surface of the substrate, wherein a top surface of the molded transparent layer is formed with a receptacle opposite to the photo sensor chip. The glass filter is accommodated in the receptacle.

A security light having optional connection to multiple power supplies. The lighting controller can sense the appropriate connected supply and automatically connect to three different power supplies which include house voltage connection through a typical junction box, a remote solar charging station, and on-board batteries that can be used as a third backup power supply. Additional implementations include power outage detection and backup illumination along with low voltage power supply from a mounting structure.

An artifact caused by secondary reflection is reduced. An imaging device according to an embodiment includes: a diffuser (110) that converts incident light into scattered light whose diameter is expanded in accordance with a propagation distance and outputs the scattered light; and a light receiver (132) that converts light diffused by the diffuser into an electric signal.

An optoelectronic module including a light emitter to generate light to be emitted from the module, a plurality of spatially distributed light sensitive elements arranged to detect light from the emitter that is reflected by an object outside the module, and one or more dedicated spurious-reflection detection pixels.

An optical receiver including an ASIC, a light detector element, and a protective mask is disclosed. The light detector element is disposed on the ASIC and has a top surface oriented toward incident light, the top surface including a portion configured to receive the incident light and via which the incident light reaches an active area of the light detector element. The protective mask is placed over the ASIC so as to (i) cover, from the incident light, a portion of the ASIC, and (ii) provide an aperture that defines an optical path for the incident light through the protective mask to the portion of the top surface of the light detector element.

A module comprises a display element, a first polarizing element, a light sensor, a transparent layer, and a second polarizing element. The display element emits a display light source. The first polarizing element covers the display element, and blocks a first phase portion of the display light source and allows a second phase portion of the display light source to penetrate. The transparent layer covers the first polarizing element. The light sensor is disposed on one side of the display element or the first polarizing element. The second polarizing element is disposed between the light sensor and the transparent layer and blocks a second phase portion of the display light source.

An optical sensing device is provided. The optical sensing device includes a first optical sensor and a filter layer. The first optical sensor is configured to receive a first optical signal. The filter layer covers the first optical sensor, and is configured to filter out the first optical signal when the first optical signal is incident on the filter layer at an incident angle not within a specific range.

A system and method. The system may include a head-up display (HUD). The HUD may include a positionable combiner optical element (COE) and a combiner alignment detector (CAD) configured to conform images displayed on the positionable COE with a view through the positionable COE. The CAD may include a mirror that moves with the positionable COE, an infrared (IR) emitter configured to emit IR pulses onto the mirror with a duty cycle of less than 1% such that an average time-based radiance of the IR pulses is compatible with a night vision imaging system (NVIS), and an IR detector configured to receive the IR pulses reflected off of the mirror.

An optical sensing device includes a substrate; a light-sensing element disposed on the substrate; a light-shielding layer disposed on the light-sensing element, including a first opening overlapping the light-sensing element; an insulating layer disposed on the light-shielding layer, including a second opening overlapping the first opening; a light-shielding element disposed on a hole wall of the second opening; and a light-collecting element disposed on the insulating layer and overlapping the second opening.
